Amazon Prime Day Oct 2022 – Early Access Deals on Synology, QNAP, HDDs, SSDs, Cameras and Network Switches

Prime Day Bargains on NAS, Hard Drives, SSDs, Cameras and Network Equipment

ANOTHER Amazon Prime Day in 2022? Yep, just a month before Black Friday kicks off and Amazon has decided to host an impromptu 2nd in-house sale event beginning on Tuesday 11th Oct until midnight on Wednesday 12th Oct (in 15 countries; Austria, Canada, China, France, Germany, Italy, Luxembourg, the Netherlands, Poland, Portugal, Spain, Sweden, Turkey, the UK, and the U.S.). No doubt many of us with a prime subscription burning a hole in our account every month will be keen to take advantage and perhaps save a few quid. Both home and business users alike often take this opportunity to upgrade or improve upon their existing data storage setup, and it should come as no surprise that several of the top-tier data storage and network tech providers in the world get involved with this annual mega sale. Unlike the likes of Black Friday, which is a longer and more widely spread bargain extravaganza, Amazon Prime Day is a shorter affair and therefore the time afforded to most buyers to make a decision on whether to buy or not can be criminally short. Today I want to highlight as many Amazon Prime Day deals that I can find below as possible. Alongside the deals that we (me and Eddie, working double time) find on network and data storage products during the event, I have also included a list of recommended hardware that you should keep an eye out for during this short sale event that is likely to spring up on lightning deals.

Important – Me and Eddie (the chaps that run NASCompares) have been running these deal-hunting pages every Prime Day and Back Friday, searching and sharing the deals we find that WE would 100% personally buy! If it’s not something we consider a deal/bargain, we won’t add it. Additionally, users can add their own deals to the list (using the gadget below). Ultimately, we do this for a mixture of reasons. We want to help people get the best storage and/or network solution for their needs, but also because by choosing to visit Amazon via the links to the deals below, any purchase you make results in a small commission fee being sent right back to us at NASCompares (which goes directly back into making great content every day). We see Prime Day and Black Friday as a means of fundraising for the site and still helping people get the best possible deal they can. If you need help choosing the right solution for your needs (and want to be 100% sure before you pull the trigger and spend anything), you can use our Free Advice service right here.

Will Synology NAS be in the Amazon Prime Day 2022 Sale and Which Solutions?

Synology of currently midway through their latest generation of hardware releases and because of this we think during Prime Day there will be a good mix of the familiar hardware that has featured in previous sales over the last 12 months, as many of the 2018, 2019, and 2020 generation of NAS in the brand’s portfolio (such as the DS218/DS218play/DS418) is still available yet also starting to look a tad dated. These big sale events always tend to result in the lowest end of the Synology range (the cost-effective J series, DS220j and DS420j) appearing on limited offers. Finally, with new releases appearing gradually in the 2022 and 2023 generation, I think we will see Prime Day deals on their home and prosumer 2/4 bay solutions. Last year’s Prime Day AND Black Friday saw the DS920+ appear on a limited offer of £55/$75 off the RRP of this device and now the device is 2 years old, it will almost certainly reappear during the Prime Day Sale again. Here are the solutions I recommend you check on intermittently if you are looking for a Synology bargain:

Synology DS220j Budget-Friendly NAS

Realtek CPU + 512MB + 2-Bay

Synology DS418 Cost-Effective NAS

Realtek CPU + 2GB + 4-Bay

Synology DS920+ Media & Business NAS

Intel CPU + 4/8GB + 4-Bay

Will QNAP NAS be in the Amazon Prime Day 2022 Sale and Which Solutions?

QNAP has revealed noticeably more of their latest generation hardware than their big competitor Synology, however, the brand is still periodically offering promotions online for their 2020 generation of hardware at a large number of retailers for its TS-x53D and TVS-X72 series, almost certainly in efforts to reduce stock levels in the run-up to newer and better premium solutions soon. Now that the QNAP TS-464 system has been revealed (although availability is still quite regionally limited) and with the summer holiday just around the corner, there will be an inevitable new product push that these products tend to receive in the last quarter of the year (starting typically around September/October), I can definitely see QNAP listing their more affordable desktop ranges in Amazon’s Prime Day sale. QNAP’s range of NAS solutions is easily one of the most diverse of any NAS brand and although it is highly unlikely that any of the TS-x64 series will be on sale this Prime Day, I DO think we will see the likes of the QNAP TS-453D, TS-233 and TS-251D appear on sale. These solutions are a good mix of old but solid, as well as new but ‘value’ series. QNAP tend to be more engaged with Black Friday than Prime Day typically, but this event is arriving at an important crossroads in the release of new hardware, so it would be a good opportunity for them to clear old generation devices that still run their QTS/QuTS 5 software.

QNAP TS-233 Cost-Effective NAS

ARM v8 + 2GB + 2-Bay

QNAP TS-453D Prosumer 4K NAS

Intel CPU + 4/8GB + 4-Bay + 2.5G

QNAP TS-364 2022 Gen NAS

New Intel CPU + 4/8GB + 3/5-Bay + 2.5G

NAS Upgrades to look for this Amazon Prime Day

Perhaps you already own a NAS Drive from Synology or QNAP, but are considering using the promotional available this Amazon Prime Day to upgrade your existing server network. Most NAS drives released in the last 10 years that arrive built on x86 64bit architecture (i.e Intel Celeron, Pentium, Xeon or AMD Ryzen, Embedded Ryzen or Radeon Powered onboard) have the facility to upgrade several internal components, or even simply add further network or storage modules to the device in order to improve performance and allow it to be more future proof. Not every NAS owner takes advantage of this, as it more often than not requires a little bit of opening the NAS up, but more modern NAS releases have SIGNIFICANTLY reduced the necessity of this (often with upgrade slots/bays being accessible externally or via the main storage bays). The improvements of increasing your memory, adding SSD caching support, improving your network connectivity and/or adding an expansion are pretty huge and particularly business users with higher frequency ad volume of connections 24×7 will see AND feel the benefits. There are ALOT of 1st and 3rd party upgrades available, so it is important to check that 1) you are opting for an upgrade that is compatible with your system and 2) that you are remaining in the warranty/support area of your NAS manufacturer. If in doubt, you can ask me and Eddie HERE about an upgrade and it’s suitability in the free advice section, but otherwise here are the four upgrades that I recommend you look for this Amazon Prime Day.

CRUCIAL DDR4 Module

Value Memory Upgrade

Sabrent 3200Mhz Heatshield Memory

Highest Performance & Design

Startech 10GbE Upgrade

VERY Affordable 10G

Seagate Ironwolf 510 SSD

Best Price vs Durability Cache Drive

Will Terramaster NAS be in the Amazon Prime Day 2022 Sale and Which Solutions?

Terramaster NAS, frankly, ALWAYS appears on sale during Prime Day and Black Friday events on Amazon with exclusive deals for their more cost-effective value series of NAS devices. They are a brand that more often than not will provide a NAS solution that is comparable in hardware to Synology and QNAP, but significantly more affordable. Much like their competitors, Terramaster is in the process of rolling out their x43 2022 generation of hardware and we have already started seeing reductions in price on the 2020/2021 generation of devices in the FX-421 and FX-422 range of solutions. Of course, the brand also provides a range of thunderbolt raid solutions, and even though I anticipate some of the NAS hardware to pop up briefly in the sales, I think it is more likely that we will see their thunderbolt RAID solutions appear more prominently. Terramaster were one of the first to show off their 2022 series of devices and will be less keen for this hardware to appear in the Prime Day sale, however, thunderbolt 4 has begun to gain traction in the post-production world and therefore TerraMaster’s thunderbolt 3 hardware is in danger of looking a little outdated and is almost certainly due an upgrade in the near future. Therefore, keep an eye out for this brand’s Thunderbolt RAID hardware this Prime Day.

Terramaster F2-210 Low Price NAS

4-Core ARM v8 + 1GB + 2-Bay

Terramaster F5-221 Budget Media NAS

Intel CPU + 2/8GB + 5-Bay + 1G

Terramaster F5-422 Affordable 10G NAS

Intel 4-Core CPU + 4/8GB + 5-Bay + 10G

Will we see many NAS Hard Drive Deals this Prime Day from Seagate and WD?

Every Amazon Prime Day we see the two big hard drive manufacturers, Seagate and WD, throw all manner of storage media deals out to the general public. More often than not, these are external hard drives and USB storage for the most part, but they always include a few hard drive offerings too. Continued hardware shortages that date back all the way to early 2020 caused by everything from the pandemic to cryptocurrency and the impact of international conflict, likely mean that much larger capacity hard drives above 10TB will either not be featured in the sale at all or be in such low quantities that you will almost certainly miss them. However, deals on WD Red and Seagate Ironwolf drives at these big promo events do still appear and more often than not at the 4TB, 6TB and 8TB levels. If you are looking at populating your brand new NAS Drive or look into upgrade your existing storage, these may well be the ones for you.

NAS Hard Drives & SSD to Look for this Amazon Prime Day

WD Red HDD

5400RPM / 1-14TB

Seagate Ironwolf HDD

5900RPM / 1-14TB / Data Recov

WD Red SSD

SATA, M.2 SATA & PCIe3 NVMe

Seagate Ironwolf SSD

SATA, M.2 SATA & PCIe3/4 NVMe

Recommended IP Cameras, Web Cameras, PoE NVR and Surveillance Equipment the Prime Day

Not a single Prime Day goes by without a huge range of IP cameras from hundreds of different surveillance brands flooding the special offers page. Thanks to efficient software controllers and much more affordable lenses being developed, you generally cannot move for IP cameras arriving on Amazon. If you are looking at starting your own surveillance setup (such as with a Synology or QNAP NAS Drive or without using a complete NVR Solution) or simply looking to expand across an existing NVR or CCTV operation you have in place, be sure to look out for Riolink and D-Link this Prime Day as these two brands provide an extensive range of very well built cameras that tend to regularly appear on Amazon’s lightning deals and occasional promotional events. Otherwise, be sure to look for any camera that supports ONVIF, to ensure that you are not locked in to any first party, cloud or subscription storage.

Surveillance/Camera Brands to watch this Amazon Prime Day

Reolink Surveillance

Smart Cameras, Value Cameras, Dual Lense

D-Link Surveillance

Cost-Effective, Wide Range, AI Services

Annke Surveillance

Excellent Nightvision Cameras – Affordable

ONVIF CAMERAS for NAS

Cameras for Synology/QNAP

Recommended Network Switches to keep an eye on this Amazon Prime Day

It has taken a while, but the affordability of 2.5GbE and even 10GbE has finally reached a point where not only are they accessible to the average John Doe/Joe Blogs, but they regularly appear on seasonal promotions. During Prime Day there will be significant savings to be made on managed and unmanaged switches from the likes of Netgear, D-Link and QNAP, who have been bolstering their portfolio to rise to the demand of remote/home works and evolved networks during the difficult first year of the pandemic as office workers evolved. Even if you are not interested in these greater than gigabit network solutions, Netgear regularly reduce the price point of their 5/8 Ports 1 GbE switches during Prime Day to just a few quid (last year there was one for a frankly comedic £6) and you will really not find a better time to start improving upon your network environment and wired land than during this event.

Switches to Look for this Amazon Prime Day

QNAP Network Switches

Smart Cameras, Value Cameras, Dual Lense

D-Link Network Switches

Cost-Effective, Wide Range, AI Services

Netgear Network Switches

Excellent Nightvision Cameras – Affordable

PS5 SSD Upgrades to Look for the Amazon Prime Day

It is almost a year now since Sony enabled the storage upgrade capabilities of the PlayStation. 5 and in that time we have seen a huge number of SSD manufacturers, big and small, release countless SSDs that all promise to be the perfect storage upgrade for your new next-gen console. In the past year or so I have conducted and published hundreds of SSD PS5 tests and during that time identified what I believe to be the very best drives for your PS5 that you should consider buying this Prime Day. Much as I mentioned earlier with larger capacity hard drives, SSDs are also suffering something of a hardware shortage and it is the bigger companies such as WD and Seagate that appear to be suffering the most as they are the ones held in the highest demand. Therefore, during Prime Day, it presents a fantastic opportunity for less high-profile brands to provide much more flexible promotional pricing and during Prime Day, you can bet your bum that there will be a wide variety of PCIe 4 NVMe M2 SSDs on offer. Remember – Resist the marketing of any brand that is not prepared to publish its performance figures and also factor in that you are going to need a heat sink for this super-fast but also high-temperature SSD for your PlayStation upgrade. Here are the SSDs I recommend that you look out for this Prime Day for your PS5.

WD Black SN850 – For Value

500GB – 2TB, Heatsink Option

Seagate Firecuda 530 – For Speed/Durability

500B – 4TB, Heatsink Option. Data Recov

Sabrent Rocket 4 Plus – Best All-Round

1TB-8TB, PS5 Design H/S, 176L NAND

GAMMIX XPG X70 – Price + Design

WD Black SN770 SSD Review

Rob Andrews — Mon, 21 Mar 2022 14:38:40 +0000

Review of the WD Black SN770 M.2 NVMe SSD for NAS Drives

I don’t think it would be an understatement to say that Western Digital and their WD Black SN850 released back in 2020 was one of the very (if not THE first) commercially accessible m.2 SSDs that allowed domestic users to hit 7,000MB/s. Getting to the top tier PCIe4 party quite a considerable time before many of the other key SSD brands, has allowed WD black to hold a considerable market share and sharing the podium with the Samsung 980 and Segatae Firecuda 530 in the eyes of most high-performance gaming and content creator buyers. However, one area that Western Digital seemingly had not fleshed out as much as their rivals were, upon entering the PCIe 4 tier, not really stretching themselves out much. Brands such as Seagate and Sabrent have introduced several different PCIe4 SSDs to their portfolios that individually towards performance, value and durability. So that was why it was great news when I heard that some 18months since the release of the WD Black SN850, Western digital have produced a more affordable and mid-range alternative PCIe 4.0 M.2 SSD in the form of the WD Black SN770. Although not commanding the same performance threshold that the SN850 can provide, it manages to still hit pretty high, is more power-efficient thanks to it’s more compact NAND and DRAMless design, lower in price and ultimately serves as an entry point for the most economical buyer to enjoy PCIe4 SSD storage. However, with the SN850 being in the market so long (and therefore pricing being varied and flexible this late into it’s life), as well as other SSDs in the market becoming equally more affordable, has WD left things a little too late to attract the value tier? Is the potential rise of PCIe 5.0 this summer/autumn and the likes of a WD Black SN950 (?) enough to keep people sat firmly on their wallets? Let’s review the WD Blck SN770 and decide if it deserves your data.

WD Black SN770 SSD Review – Quick Conclusion

You can not really fault the WD Black SN850 SSD in terms of what Western Digital has said this drive can do, as it not only meets those expectations consistently but also exceeds it more often than not by a few degrees. The WD Black SN850 SSD is not going to challenge the current generation of 7K performing drives, but then it is not trying to. This is a mid-range SSD that serves as an entry point into PCIe 4 storage for many and in that tier of storage, the WD Black SN770 SSD unquestionably succeeds. That said, this SSD is at this price and at this power efficiency by design and the fact it took WD this long to release a 2nd entry into their PCIe4 gamer/content-creator portfolio leaves it in danger of being overlooked by the bigger, bolder, faster and ultimately preferable WD Black SN850 SSD. This is made double impactful when you see the SN850 regularly on sale at numerous retailers at any time thanks to its longer time in the market. The SN770 SSD stands as a great SSD that allows lower specced PC users to spend their budget wisely on a suitably SSD for their needs, just don’t overlook that this SSD comes with a lower glass ceiling than many higher-performing SSDs in the market right now at a similar price.

WD Black SN770 SSD Review – Retail Packaging

Unsurprisingly, Western Digital has been fantastically uniform about the packaging and presentation of the WD Black SN770 SSD, largely repeating the same design of the retail pack that was found in the WD Black SN850. Western Digital first coined the colours system of differentiating their HDD/SSD ranges a decade ago and although a few brands have attempted to emulate this simple but effective means to understand the intended purpose of a drive quickly, no one has quite nailed it as well as WD and their portfolio colours system (Red = NAS, Blue = Domestic/Home PC, Purple = Surveillance, Gold = Data Center, Green = Power Efficient and Black = Gamer and Content Creator).

Indeed, given the 18 months between the release of these two SSDs, it is still pretty surprising that WD has stuck with the techie/PC Gamer designed aesthetic of the package. Plenty of highlighting of the performance, lots of branded logos shining and a very confidently presented retail kit. I do wonder how many buyers (unaware of the distinction in performance and value between these drives) might purchase incorrectly because of this similarity, but hopefully the preponderance of eShop purchases for an SSD like this should mitigate it.

The retail kit for this SSD is a little thin on the ground in terms of contents (fairly standard with m.2 SSD and their stripped-down design for reasons of cooling and efficiency) but the drive arrives well protected and held between two layered windows of hard plastic. Although not crush-proof, you would need to be willfully destructive with this package to make any damage to this SSD really.

Alongside the WD Black SN770 SSD itself, the only other item of note in the retail package is the warranty and first-time setup document. Even then, this is pretty barebone and support/guides on installation are best accessed on WD’s own website (As well as using the WD Dashboard tool to update your firmware as appropriate). The WD Black SN770 SSD arrives with 5 years of manufacturers warranty (as well as a terabytes written threshold to that warranty as found with most modern SSDs) which is pretty standard. I will add that WD’s warranty process (personal experience on two occasions for an SSD and an HDD) has been faultless and with a fast turnaround.

The WD Black SN770 SSD itself is surprisingly barebones (even for an M.2 SSD which is typically barren at the best of times) with the 1TB model that I used for this review only really featuring three notable components on the PCB. We will talk a little later how this differs from the WD Black SN850 SSD and how this has impacted performance and the price tag, but for now, let’s drill a little deeper into the build of the SN770.

WD Black SN770 SSD Review – Design

The WD Black SN770 SSD is a 2280 (22mm x 80mm) drive that arrives in 500GB, 1TB and 2TB. Hardware architecture and the build of the SSD is largely identical in each capacity (with a minor difference in durability that will get touched on later) but it is by far one fo the clearest and cleanest SSDs that WD has put out for years. Now, a big part of that is that the SSD does not feature onboard memory (relying on using a portion of host system memory when in operation, a process known as Host Memory Buffer or HMB) so it needs to make sure the controller does not get overworked and spacing out the components becomes more important to maintain cooled efficiency. This is also a possible reason for all three tiers of this SSD arriving singled sided with a large NAND module (eg in this 1TB there is 1x 1024GB SanDisk NAND instead of the 2x 512GB you might find in others).

Flipping the SSD shows that aside from more branding and all of the WEE, ROHS and QC type certifications, there is no further components of note. A 1TB SSD arriving single-sided is not unusual, but that single NAND design does set it apart from other 1TBs on the market notably.

The WD Black SN770 SSD also arrives with PCIe Gen 4 architecture, as well as the NVMe 1.4 revision. PCIe Generation 4 allows a potential bandwidth of 8,000MB/s (8GB/s) and although the SN850 before it saturated the bulk of that at 7,000MB/s+, the WD Black SN770 hits a maximum 5,150MB/s. The M.2 SSD connection with the PC however is much more efficient and (as will be shown later and in a comparison article with the SN850 soon) although my mid-range 11th Gen i5 CPU PC for testing only JUST hit the 7K mark on the SN850, it comfortably exceeded the reported maximum on the SN550, thanks to that more efficient and streamlined architecture. So, if you are running a middle of the road PC that perhaps was never going to max out the WD Black SN850 SSD, the WD Black SN550 makes a compelling argument as a more realistic choice. Let’s examine those individual on-PCB components.

WD Black SN770 SSD Review – Hardware Specifications

As WD generally utilizes only in-house components and manufacturing teams on their drive media, the WD Black SN770 SSD is architecturally similar in parts to several other SSDs in their past/present portfolio, including the WD Blue NVMe and WD Black SN850 before it. Where most SSDs would have the onboard to act as a buffer of the controller when pushing through all that data/bandwidth, the WD Black SN770 has a blank space (with the logo, serial, etc) and the NAND remarkably far away from the controller. Thanks to the drive making use of the host system memory, the hardware specifications of the WD Black SN770 are a little lighter than most.

The highlights of the SN770 Hardware Specifications are:

Available in 250GB-500GB-1TB-2TB
WD NVMe Controller
Host Memory Buffer
Kioxia BiCS5 112L TLC NAND
2280 Length
PCIe Gen 4 x4 NVMe 1.4
1,750,000 MTBF
0.3 DWPD (Capacity Dependant)
200-1200TBW (Capacity Dependant)
5yr Warranty

The WD Black SN770 arrives with a tweaked version of the in-house Sandisk (WD own SanDisk) NVMe SSD Controller that, in conjunction with that host client system managed memory architecture, allows the PCIe 4 SSD to comfortably hit that 4500-5000MB/s performance point. The 500GB model does aim a little lower in both read and write (as is fairly normal in these SSDs in their lowest capacity) but this controller is still a great example of the brand’s in house architectures, particularly when Phison’s own E18 and E16 controller make up the bulk of other SSDs in the PCIe 4 tier right now. The SN770 is not the only DRAMless SSD in the market, but IS one of the highest performing examples right now and one of few in the PCIe4 tier. This controller on the more affordable WD Black SSD still arrives with advanced power management to remain cool and efficient during use, as well as enabling thermal throttling if the temp creeps up that prioritizes data integrity over speed. There is also support for standard SSD management components such as Trim, SMART and secure erase capability via the Format NVM command. It all seems to be comparable vs the SN850 until you notice that the WD Black SN770 does not support AES 256-bit hardware encryption, likely down to it’s demand on memory being unsupportable here. What is the impact of the SN770 lacking DRAM, Host Memory sharing and are there limitations to this SSD?

What Are the Advantages and Disadvantages of an SSD without DRAM?

So, let’s drill down into those specifications a little. What is the impact of the WD Black SN770 not having its own onboard memory? How exactly does the controller manage tables of data and indexes on the fly? An SSD, much like the PC or mobile device that you are reading this review on, is typically comprised of 4 main components internally. Namely the CPU, the Memory, the storage and a board for it all to live on and communicate on. SSDs are much the same with the CPU being replaced by an SSD controller, the storage being replaced by the NAND, the motherboard being replaced by the PCB and the memory being replaced by SD-RAM/DRAM. The DRAM on an SSD allows the Controller to have a workspace to construct and form the instructions that it needs to handle instructions in all directions. Below is the SN850 with it’s 512/1/2GB of DDR4 memory (capacity dependant) and the DRAMless design of the WD Black SN770:

WD Black SN850 SSD	WD Black SN770 SSD (No DRAM)

Now the WD Black SN770 SSD still needs memory, but in order to facilitate more efficient power consumption, make it more affordable and still allow higher performance to be achieved, this SSD reserves an area of the memory in the host system (PC etc) and this is used in the same way as the memory that would have been used by the traditional DRAM of other SSDs. Additionally, it uses considerably less memory than the inclusive memory of most SSDs that feature DRAM onboard and it is fairly rare for anyone but power users to be using the entirety of their system memory, so this serves as a much more efficient and resource level approach to running a PCIe 4 SSD and still getting better than PCIe speeds possible.

Now as well and good as this all sounds, Host Memory Buffer (HMB) architecture SSDs such as the DRAMless WD Black SN770 is by no means a perfect ideal basis of storage for prosumer and power-users. Smooth running of the SSD is not possible when the memory of the client machine is at a high % of usage. Additionally, you need to ensure that your host system supports HMB in order to ensure the drive is not going to immediately bottleneck. That is why the WD Black SN770 is fully supported on PC but PS5 storage upgrades with this SSD are not recommended, as SMB is not readily available in the close console system design. Another downfall of HMB SSDs in the eyes of power-users is that sustained/constant activity with this lack of onboard memory faces diminishing returns. So operations that are larger in scope of sustained over a longer period of time result in the memory-flushing that this smaller area on onboard memory needs to be too low in frequency for higher performance to be maintained. The result is that the high performance of these more enduring operations will slow down more and more as they continue. PC gamers will not notice in instances of gameplay when the loading of an AAA title is higher front-loaded, but content creators and editors that are editing larger projects off the SSD in video production software will notice this slowdown over time. Let’s discuss the other key components of the WD Black SN770 SSD.

Interestingly, when it comes to the NAND onboard, the WD Black SN770 arrives with improved density NAND compared with the SN850 SSD. The SN770 features a single 1024GB block of Kioxia BiCS5 112L 3D TLC NAND, notably higher than the Kioxia BiCS4 96-Layer TLC which means this SSD has twice the potential write performance ability – which given the lack of memory is going to be invaluable. Equally, the fact that they have opted for 1 block of NAND in the 1TB sample here rather than spreading across multiple modules is likely linked to that lack of memory also. The WD Black SN770 SSD can utilize upto 64MB of system memory and although this will certainly get sporadic access and light-medium usage sorted, that is going to be problematic in higher usage frequency. Let’s take a closer look at how the WD Black SN770 and WD Black SN850 SSD compare on specifications and reported throughput, IOPS and durability.

How do the WD Black SN850 and WD Black SN770 SSD Compare?

Unsurprisingly, the more expensive WD Black SN850 is the higher-performing SSD when compared with the SN770. This difference in performance also extends vitally towards sustained use and users who are weighing up the pros and cons of each will crucially need to think about the potential performance and workload of their current system. The reported performance and durability below represent maximums and although the highest points of sequential throughput and 4K random IOPS on the SN850 SSD are only achievable of particularly powerful systems, the high points of the SN770 are actually more achievable on mid-range systems.

The big takeaway here is that if the system you intend to install the WD Black SSD into is NOT prosumer grade, then the maximum read/write that you will see in either the WD black SN850 or SN770 is going to be a lot closer than you might think and any additional price, power use and heat that the WD Black SN850 generates might be to little benefit. Additionally, the durability on the WD Black SN770 SSD is largely the same as the SN850, despite its lower performance, so you won’t be seeking out any additional workload out of the more efficient drive. Let’s get the SN770 SSD into the test machine and see how it performs.

WD Black SN770 SSD Review – Testing & Benchmarks

Now we know how the WD Black SN770 SSD is built, it’s time to put it through its paces. I used a midrange test machine and several different pieces of test benchmarking software (CrystalDisk, ATTO, AS SSD, AJA) to measure how this DRAMless SSD performed.

Test Machine:

Windows 10 Pro Desktop System
Intel i5 11400 Rocket Lake – 6-Core 2.6/4.4Ghz
16GB DDR4 2666MHz Memory
Intel B560M mATX Motherboard
OS Storage, Seagate Firecuda 120 SSD
Test SSD connected to Secondary PCIe Gen 4×4 M.2 Slot

You can hear more on how the test was conducted and those results in full in the video below:

Using CrystalDisk, we got a good measure of the drive and verified that this PCIe Gen 3 x4 SSD was indeed using the 4×4 lane. Additionally, the temp averaged out around 45 degrees between each test being conducted.

Another important area to note whilst the WD Black SN770 SSD was being tested was that the temperature of the controller increased notably during each sustained test. I used a standard $10 m.2 heatsink and even with a 1-minute cool-down between each test, the SSD reached the 60 degrees mark very quickly.

The first range of tests were using ATTO Disk benchmark and three separate file sizes were used, 256MB, 1GB and 4GB. Each test was conducted upto 64MB I/O and we recorded the sequential performance and the IO/s:

ATTO Disk Benchmark Test #1

256MB File PEAK Read Throughput = 4.91GB/s

256MB File PEAK Write Throughput = 4.62GB/s

ATTO Disk Benchmark Test #2

1GB File PEAK Read Throughput = 4.88GB/s

1GB File PEAK Write Throughput = 4.62GB/s

ATTO Disk Benchmark Test #3

4GB File PEAK Read Throughput = 4.88GB/s

4GB File PEAK Write Throughput = 4.49GB/s

The next test of the WD Black SN770 SSD involved CrystalDisk Benchmark and I tested a 1GB, 4GB and 16GB File scale.

CRYSTALDISK MARK 1GB TEST

CRYSTALDISK MARK 4GB TEST

CRYSTALDISK MARK 16GB TEST

Next, I switched to AS SSD benchmark. A much more thorough test through, I used 1GB, 3GB and 5GB test files. Each test includes throughput benchmarks and IOPS that are respective to the larger file sizes (important, if you are reading this and trying to compare against the reported 4K IOPS from the manufacturer).

AS SSD Benchmark Test #1

AS SSD Benchmark Test #2

AS SSD Benchmark Test #3

Ordinarily, I would introduce tests like BlackMagic and AJA into the mix here, but even a short burst of testing on an NVMe like this would over saturate the cache memory on board. Nevertheless, in the short term we still could ascertain the reported performance on 1GB, 4GB and 16GB file testing was:

4GB AJA File Test Results (Peak) = 4,357MB/s Read & 4,711MB/s Write

16GB AJA File Test Results (Peak) = 4,364MB/s Read & 4,715MB/s Write

16GB AJA File Test Results (Peak) = 4,715MB/s Read & 4,371MB/s Write

The overall performance throughout all testing largely exceeded the reported maximum by WD themselves, which I was very impressed by. Sustained performance was unsurprisingly poorer as the borrowed system memory and controller became overworking in the larger and longer-running tests, but in shorter bursts, the drive clearly did what they said it can do and more. Let’s conclude today’s review and work out what we think of the WD Black SN770 SSD.

WD Black SN850X SSD Review & Testing

Rob Andrews — Sat, 06 Aug 2022 12:29:29 +0000

Review of the WD Black SN850X PCIe Gen 4 NVMe SSD

Before you sink your teeth into the review of the WD Black SN850X SSD, it is important to understand that this is not the same as the widely available and industry applauded SN850 SSD. On the face of it, the difference is simply the ‘X’ prefix – Is that really much of a difference? I think it would be pretty fair to say that when the PCIe 4 generation of SSDs hit the consumer market, the one that made the BIGGEST (and earliest) splash was the WD Black SN850. Originally released in Autumn 2020, although it wasn’t the first PCIe4 M.2 SSD, it WAS the first commercially available drive to hit 7,000MB/s (followed incredibly closely by Samsung’s 980 Pro). Now, 2020 was quite a while ago now (give or take a pandemic or two) and in that time a wide variety of top tier (and indeed mid-low tier) brands have expanded in the PCIe 4 SSD tier, challenging the WD Black SSD in terms of performance, durability and price. The 2020 released WD Black SN850, although still hot in the basket of buyers of PS5 storage and regularly on sale during Black Friday and the like, is no longer the groundbreaking drive that it once was. And THIS with where the WD Black SN850X comes in. Now, the SN850X is NOT designed to be a replacement to the SN850. In fact, in recent months, we saw Western Digital roll out the WD Black SN770, a DRAMless, more efficient and more affordable alternative. The SN850X is designed to complete the product family in the PCIe4 M.2 NVMe tier and whereas the SN850 gains notoriety and licencing with the Sony PS5, the WD Black SN850X has its sights squarely on the Premium PC Gamer and Premium Performance tier exclusively (content creators, professional streamers and eSports). But is the WD Black SN850X really that much different? Is this a cash grab or is this a legitimate answer by WD to challengers in the PCIe4 SSD tier? Let’s find out.

Note – Now that the WD Black SN850X SSD has been released, is the 2020 released WD Black SN850 SSD Still Worth Your Money in 2022/2023? Find out HERE on the blog or in 4mins HERE on YouTube, or the full performance test HERE.

WD Black SN850X SSD Review – Quick Conclusion

The WD Black SN850X is a great SSD – If you came to this review wondering whether it is a good drive, I can unquestionably say it 100% is. You are getting a much more evolved and current upgrade on the already popular SN850 and a drive that is a much more comparable drive to recent releases from the likes of Seagate Firecuda 530, whilst also throwing significant shade at the Samsung 980 Pro into the bargain. Digging a little deeper into the specs of the SN850X itself shows that a handful of strategic (and of course more recently developed improvements at the WD R&D level) are what push this drive much further along in the food chain that then2020 released SN850. That said, some areas of the SN850X have seen little or no change since the SN850, such as near identical durability ratings (TBW/DWPD) and the drive still running a little hotter than it’s competitors. Had WD released the SN850X at the tail end of 2021 (when information of the X version of the WD Black SSD first emerged), then I think it would have made a considerably bigger impact! Nonetheless, WD is riding something of a hot streak with their WD Black PCIe4 series right now (the release of the more affordable HMB built SN770 and the SN850 getting official PS5 Compatibility by Sony), so releasing the WD Black SN850X right now, as the PCIe5 generation drags its feet commercially due to hardware shortages and the pandemic affecting the supply chain) makes alot of sense too. The SN850X arrives with a price point that, when stacked up against the 2yr available SN850, may seem a pinch high, but it won’t be long till we see this newly established PCIe4 WD Black family more organically tier its pricing. Bottom line, if you were considering the SN850 SSD for your gaming or content creation setup (or indeed any other setup that will leverage ‘write’ activity) I would strongly recommend stretching your budget a pinch further and opting for the WD Black SN850X SSD. It is worth remembering though that unless you are running a particularly powerful setup, you will only see improvements in the SN850X over the SN850 in write performance, with only marginally improvements in read rates.

The external packaging of the WD Black SN850X SSD is near enough identical to that of the WD Black SN850 and SN770, with Western Digtial’s stylized branding for the series out in full force. With the recent official support of the WD Black SN850 by Sony for the PS5, this should mean that the external packaging of the older drive will change to blue/white, but for now this new drive blends into the same design choices as the rest of the WD Black series.

The retail packaging also makes plenty of noise about the promised performance on the SN850X, with information on the front about the promised maximum 7300MB/s Seq Read and further details on the back regarding the durability, IOPS and further hardware specifications. Again, all this will be massively familiar to anyone who has purchased a WD Black SSD previously.

The contents of the retail package are pretty light, with the SN850X SSD arriving on its own in a plastic protective shell and just a document regarding the 5-year inclusive warranty. If you were to purchase the heatsink-equipped version (only available in 1-2TB models), that arrives pre-attached at the factory level.

On its own, the WD Black SN850X is quite a modest-looking drive and even in the 2TB capacity module that was featured for this review, only a single side of the SSD is occupied by chips/components on the PCB.

That is really all you can say about the packaging and presentation of the WD Black SN850X. It is quite a modest kit and most of the value/impression of this device is left to the hardware onboard and how that translates to performance. Let’s take a closer look at the drive itself.

WD Black SN850X SSD Review – Design

The WD Black SN850X SSD is a PCIe Gen 4×4 M.2 Key NVMe SSD that is completely backwards compatible with PCIe Gen 3×4 SSD slots where necessary (though crucially not M.2 SATA) that improves upon the architecture of the WD Black SN850 in a few key areas to produce a higher performance point in most of the key areas you want/need. Running on NVMe 1.4 architecture, the drive is reported to be the fastest PCIe m.2 SSD that Western Digital has ever produced and manages to saturate a maximum 7,300MB of the potential 8,000MB of PCIe 4×4 lanes.

The top of the SSD has the large ‘WD Black SN850X’ label that you do NOT need to remove when in operation (with or with a heatsink). Removing this label shows us a tightly packed arrangement of components/cells on the SSDs PCB. An SSD is not unlike a PC in it’s architecture, with a Controller (CPU), DRAM (Memory) and NAND (storage space). There are additional power/transistors in place to aid smooth operation, but ultimately these are the key components we need to focus on.

As mentioned earlier, if we flip the SSD over, we can see that this 2TB SSD is single-sided (i.e just a bare board on the back). The WD Black SN850X 4TB model IS double-sided, arriving with 4x 1TB NAND modules and an additional DDR4 Memory module, but this 2TB does an excellent job of keeping things nice and compact, whilst allowing much more direct, manageable and efficient heat dissipation. Something we will DEFINITELY touch on later.

The SN850X also benefits from being a completely first-party/in-house SSD. Many PCIe 4 SSDs that have arrived on the scene in the last two years can be broken down into two strict camps. The larger one is made up of brands such as Seagate, Sabrent, ADATA, Patriot and more who rely on 3rd party companies such as Phison and Innogrit to provide components (eg SSD controllers). The other smaller camp in the world of SSDs is comprised of brands such as Western Digital, Samsung and Crucial who tend to rely much more (often exclusively) on first-party controllers and NAND for their drives, allowing them to craft media that is much more precise in it’s execution, as well as allows them better quality control, supply and pricing. There are benefits to either approach in SSD design, but many users like the idea of a near complete or near enough completely in-house designed SSD.

So that is the physical design of the WD Black SN850X SSD. But what about the hardware components themselves? Does the WD Black SN850X SSD change things up much from the SN850? Let’s find out.

WD Black SN850X SSD Review – Hardware Specifications

The WD Black SN850X SSD is highly comparable to the older WD Black SN850, but with a few improvements along the way. Here is how the two SSDs stack up in initial hardware specifications:

Brand/Series	WD Black SN850X	WD Black SN850
PCIe Generation	PCIe Gen 4×4	PCIe Gen 4×4
NVMe Rev	NVMe 1.4	NVMe 1.4
NAND	3D TLC NAND (Layer Count TBC)	Sandisk/Kioxia BiCS4 96L 3D TLC NAND
Max Capacity	4TB	2TB
Controller	WD Black G2 (TBC)	WD_BLACK G2
Warranty	5yr	5yr

I know the above might seem needlessly technical, so below we can bring the most important considerations into sharper focus.

Hardware Focus of the WD Black SN850X SSD

The onboard SSD controller of the WD Black SN850X is a little bit of a mystery (at least at the time of writing this article). Arriving with the Sandisk model ID ’20-82-20035-B2′, this is practically no information online currently about this component. This is not unusual, as Western Digital are famously secretive about the make-up of its components (compared with the bulk of SSD brands that rely on controllers developed by Phison or Innogrit). At best guess, this SSD controller is an improvement/variation of WD G2 NVMe Controller found in the SN770 and SN850 (the 20-82-10035-A1 or 20-82-10081-A1). Almost certainly further information on this controller will arrive as this SSD enters circulation and I will update this area of the review with more (with references etc). In terms of performance (covered in more detail later) it still maintained a similar level of sustained Read activity as the SN850 throughout testing, but with a clear and substantial increase in write performance in our modest test machine.

This controller is also accompanied by Micron IFB75D9XPG DDR4 DRAM that scales alongside the storage capacity (i.e 1GB DDR4 > 1TB Capacity, 2GB DDR4 > 2TB Capacity). This already puts it at a tremendous advantage over the WD Black SN770 released a short while ago that required increased cooperation with the host system with the use of host memory buffer (HMB). This combined with an improved controller likely results in this drive providing the best sustained performance possible in a WD Black m.2 NVMe SSD yet

The storage NAND used by the SN850X is Sandisk 006761-1T00, BiCS 3D TLC. The layer depth of this memory is still being investigated (once again, WD being remarkably secretive) but based on the performance capabilities, is almost certainly 112-layer or 162-layer depth. The older SN850 arrived at 96L and the recently released SN770 arrived with 001397 1T00 112-layer BiCS 3D TLC memory). I’ll revisit this area o the review later and update as more details on this are revealed.

The 2TB model of the WD Black SN850X that was used for this review arrived with two 1TB blocks and this is what allowed this good-sized capacity drive to remain single-sided. The 4TB model unsurprisingly needs to spread itself out a bit and also is the only capacity in the SN850X not to include the optional official LED-equipped heatsink. So, how does this SSD compare with the current and more popular PCIe4 M.2 NVMe SSDs in the market right now?

WD Black SN850X vs Seagate Firecuda 530 vs Samsung 980 Pro SSD

Before we conduct our own testing on this SSD, Let’s take a closer look at the reported specifications and benchmarks first. The WD Black SN850X SSD arrives in multiple capacities (below). The Prices currently are a little inconsistent (with each higher capacity tier actually having a higher price per GB – quite unusual) likely due to the continued global hardware shortages, the Pandemic’s effect on the supply chain, the effects of Chia crypto has on SSD availability in 2021 and almost certainly the ongoing issues surrounding Taiwan and China! Below is a breakdown of how each SSD from Seagate and Samsung compares with the WD Black SN850X:

*TBC at the time of writing and will be addressed/confirmed later. The video below will break down the definitions and meaning of the terms used throughout this review and the comparison tables

** Pricing for the SN850X is quite varied online at launch and regardless of tax and currency exchange rates, the pricing here (taken from the official WD store) seems a bit uneven. This will hopefully even out soon.

So, first up we can discuss the available capacities. The Samsung 980 Pro still continues to stick at the maximum 2TB capacity line, whilst also being available in the smallest capacity in the lineup (in a 250GB form). Seagate and the Firecuda 530 arrive in the most well-spread range, starting at 500GB and ending at 4TB. This leaves the WD Black SN850X somewhere in the middle with the 1TB, 2TB and 4TB options. All this said, in terms of pricing, the WD Black SN850X overall arrives at the best Price per TB of the three – though pricing at the launch of the SN850X has been a little inconsistent depending on where you are in the world. Next there is the subject of durability and the WD SN850X still has the same DWPD/TBW/MTBF rating of the 2020 released SN850 (matching the TBW of the Samsung 980 Pro), which although pretty good, is still less than half that of the Seagate Firecuda 530 – Still the more high endurance PCIe4 M.2 SSD in the 7K performance bracket even a year since release. Let’s compare the three drives in terms of maximum rated performance. These are the quoted performance figures provided by each brand and in single drive test environments, with exceptionally high-end CPU+Memory combos that can be referenced on their own resource pages.

The first thing we need to immediately highlight is that despite the WD Black SN850X certainly improving on the performance provided by the 1 years older SN850 and 2 months older SN770, it is still not the fastest PCIe4 M.2 NVMe SSD in the consumer market right now, arriving just a few hundred MB under the Seagate Firecuda (which arrives with 176L NAND that allows a pinch more in terms of traditional transfer rates). In terms of the IOPS though, the WD Black SN850X absolutely STORMS IT, with a higher 4K random read and write at every single capacity tier. The Samsung 980 Pro ends up looking increasingly overshadowed, unfortunately, leaving many to wonder if Samsung is going to challenge this with a Samsung 990 Pro, EVO or Plus, or go ahead and concentrate on making a bigger splash on Day 1 for the PCIe5 generation (as they did in the PCIe4 gen in 2020). It is also worth remembering that these reported performance figures are based on exceptional high-end PCs and configurations, that only a small % of users in the consumer section will have in place. So what about in more common setups? How does the WD Black SN850X perform in a relatively pedestrian Intel i5 Windows 10 PC Configuration? Let’s find out.

Testing the WD Black SN850X m.2 PCIE4 NVMe SSD

The WD Black SN850X 2TB was provided by WD for this test and it was tested using multiple benchmark tools, from a cold boot, in the 2nd storage slot (i.e not the OS drive). Each test was conducted three times (full details of this are shown in the YouTube Review of the WD Black SN850X over on NASCompares):

Test Machine:

Windows 10 Pro Desktop System
Intel i5 11400 Rocket Lake – 6-Core 2.6/4.4Ghz
16GB DDR4 2666MHz Memory
Intel B560M mATX Motherboard
OS Storage, Seagate Firecuda 120 SSD
Test SSD connected to Secondary PCIe Gen 4 M.2 Slot

Here is the Video Review of the WD Black SN850X SSD and PC Benchmarks:

Using CrystalDisk, we got a good measure of the drive and verified that this PCIe Gen 4 x4 SSD was indeed using the 4×4 lane. Additionally, the temp averaged out around 48C between each test being conducted, with the drive being encased in a regular Eluteng M.2 $10 heatsink. Much like the WD Black SN850, this new entry into the WD Black series certainly ran quite hot.

The first tests were conducted using the ATTO disk benchmark software. The first was a 256MB test file size and below is a breakdown of the transfer rates and IOPS. The 2nd Test was a 1GB test file and finally, the last test was with a 4GB test file. The system was given 1-minute cool downtime between tests, no screen recording software was used (remove overhead) and a heatsink was used throughout (no reboots). Write performance continued to impress throughout, but the read performance was a pinch lower than expected, likely down to the i5 in the system compared with the Xeon/Ryzens that many Manf brands choose to max-benchmark their drives with

ATTO Disk Benchmark Test #1

256MB File PEAK Read Throughput = 6.41GB/s

256MB File PEAK Write Throughput = 6.22GB/s

ATTO Disk Benchmark Test #2

1GB File PEAK Read Throughput = 6.42GB/s

1GB File PEAK Write Throughput = 6.21GB/s

ATTO Disk Benchmark Test #3

4GB File PEAK Read Throughput = 6.41GB/s

4GB File PEAK Write Throughput = 6.21GB/s

Next, although the ATTO tests were quite good, I moved on to the Crystal Disk Mark testing to see how well it would handle our next barrage of tests. The first test was the 1GB file testing, which measured both sequential and random, as well as the read and write IOPS. Test were conducted on a 1GB, 4GB and 16GB Test File. I also included a mixed 70/30 read and write task to give a little bit more of a realistic balanced workload. These tests were conducted with 1-minute cooling break in between. The WD Black SN850X did not crack the 7,000MB/s threshold on the mid-range test PC, but once again, the Write performance was very impressive indeed!

CRYSTALDISK MARK 1GB TEST

CRYSTALDISK MARK 4GB TEST

CRYSTALDISK MARK 16GB TEST

AS SSD Benchmark Test #1

AS SSD Benchmark Test #2

AS SSD Benchmark Test #3

1GB AJA File Test Results (Peak) = 5894MB/s Read &5721MB/s Write

4GB AJA File Test Results (Peak) = 5861MB/s Read & 5759MB/s Write

16GB AJA File Test Results (Peak) = 6008MB/s Read & 5734MB/s Write

Overall, the WD Black SN850X was certainly able to provide some solid performance, as well as potentially exceed the test figures here on a more powerful machine. Given the reported Read and Write statistics that the brand has stated publically, I think there is enough evidence here to back up those claims. IOPs were a little lower than I expected, but again, we were testing very large file types, so this would have to be taken in context. I do wish most SSD brands provided benchmarks for different tiers of systems, rather than only stating the systems at the very, VERY top end. It makes sense, to run the drive in a system without any potential bottlenecks, but a 2nd or even 3rd round of test results that cover more mid-range or domestic systems would give users better scope of the drive’s potential in their own setup. Nevertheless, the peak performance of the WD Black SN850X was still exceptionally high AND sustained in my mid tier test machine and certainly a great indication that this drive will consistently live in the 6,500MB/s+ area in read/write in even the most modest setups.

WD Black SN850X SSD Review – Conclusion

PROs of the WD Black SN850X SSD

CONs of the WD Black SN850X SSD

High Performance, even in mid-range PC hardware
Excellent improvements in Write Performance vs the SN850
4TB option is finally available in the WD Black series (long overdue)
New SN850X entry into the WD Black PCIe4 family will improve price structure positively for the SN850 and SN770
PC client tool improvements and excellent features in Game Mode 2.0
1st class produced drives = best availability and pricing normally

Still runs quite hot, much like the SN850 does
Still not the fastest PCIe4 M.2 SSD in the market
The durability, though good, is still not quite as high as other SSDs in the market
