If one thing has become abundantly clear in the world of network-attached storage even early in 2021, it is the Synology have really started focusing heavily on the enterprise sector. As a brand, Synology has tended to juggle three very important areas of storage, namely home, small/medium business and enterprise solutions. However, the recent releases from Synology have largely delved into that latter department more and more, with Synology launching three new enterprise rackstation solutions in January 2021, alongside unveiling their new hard drive range for use in these top-tier systems. The new Synology RS3621xs+ rack mount 12 bay solution follows a popular predecessor in the RS3617xs+ solution released in 2017. Arriving with a more balanced hardware vs storage architecture than the OTT solutions released in the last 2 years (see the SA3400, UC3200 and FS6400 for example), people have been waiting on an upgrade on this series for a while. Although the newest generation brings with it a few improvements on an already popular recipe, new storage limitations and some changes in the Synology ecosystem may not be for everyone. So let’s take a closer look at this new rackmount solution and see if the RS3621xs+ is another solid step forward from the brand in its efforts to conquer the enterprise market.

Synology RS3621xs+ NAS Review – Quick Conclusion

The Synology RS3621xs+ Rackstation is another solid and reliable piece of kit from one of the biggest brands in NAS and although I did not expect it to disappoint, it is still arguably the teeniest bit safe as an upgrade over its predecessor. An improved CPU, improvements on quality and quantity of memory and the ways in which the system can be upgraded are always welcome. But if you already own the Synology RS3617xs+ that came before it, there are not going to be enormous improvements here that warrant an expensive upgrade. Additionally, the policy of the newest generation with its rather strict policy on compatible hard drive media might not be for everyone and being more desirable to those more committed to the Synology ecosystem. An excellent piece of hardware that nevertheless manages to play it safe and be controversial at the same time.

Synology RS3621xs+ Rackmount NAS Review – Retail Packaging

The RS3621xs+ NAS arrives in a staggeringly large shipping container. Generally, I don’t review Enterprise-class hardware on the blog (favouring YouTube normally), as I feel this kind of hardware is tricky to review without undermining the larger-scale visual scale of things. However, I was genuinely excited to get my hands on this device, as it’s predecessor, the RS3617xs+ (and the RS4017xs+) were remarkably popular devices for those users who jumped from SMB to Enterprise. The shipping box is fantastically well protected and contains multiple layers of cardboard and protection.

Inside we find the RS3621xs+ NAS of course, but also around 50% of the box is occupied with protective foam (protection from shock/movement damage in transit of course). The system arrives unpopulated, but given the recent release of Synology HAT5300 hard drives and strict compatibility on this system for those drives, I do wonder how long it will be before Synology consider fully/partially populated systems. Nevertheless, if they do, this is more than enough protection in transit for that!

Strip away all the cardboard and we find the unit, encased in foam and a box of accessories.

Inside the box of accessories, we find a marginally thinner collection of bits than usual.

In full, you find a Setup Guide, First Time tips sheet, screws for 2.5″ and 3.5″ media and two mains power connectors (as this is a redundant PSU device). There are not HDD tray keys, as this system uses manual click locks on each bay and there are not ethernet cables. Now, this is a minor grip that some have raised online, but Synology has starting reframing from including ethernet cables in their rackmount solutions lately. Now, there is a very positive argument to be made for this that they are preventing waste in the unnecessary use of ethernet cables that might be superfluous and/or are too short for a particular setup. However the flip side is that some business users will just be irritated not to have these on hand (especially given that the bulk of switches, NICs and routers do not include cables either. It’s a very, VERY minor point, but certainly raised by some

Ultimately though, it’s all fairly safe, solid and standard. Let’s take a look at the design of the system

Synology RS3621xs+ Rackmount NAS Review – Design

The front panel of this full depth rackmount NAS server is rather understated. Synology has never entertained LCD panels or any hands-on control panels on their rackstation series and the RS3621xs+ is no exception. The system has 12 main SATA storage bays, power and mute controls, as well as LEDs to denote access and activity. It’s a sleek and clear design that also features quite a lot of passive ventilation on each tray.

On the left-hand side of the system, you will see both a power button and a mute button. The former is pretty obvious, but it is only really in rackmount systems that we find the option to mute alert noises. This is generally because rackmount systems are usually set up in tower cabinets, as well as in relatively inaccessible locations. When an alert happens, the reason will be readily apparent from the DSM GUI. However, with one of many different reasons (drive error, temperature, access issue, etc), many users will want to mute the device at the hardware level, before logging in to address the matter via the software. It’s a longstanding feature of rackmount that always leaves me a little surprised when I still see it today.

The Synology RS3621xs+ does not arrive with rails included (two versions available from Synology), but does feature the side handled on either side of the chassis. This is generally to aid alignment in a rack cabinet, as well as grip in the case of sliding rails.

As mentioned, each of the SATA drive bays features its own clicking lock mechanism (no key-lock). It’s a shame we aren’t seeing any SAS HDD support hear, but then again you do have the SA series of solutions from Synology for that.

Each tray features screw holes for 2.5″ and 3.5″ media, though the subject of compatible and supported Hard Drive media is something that the Synology RS3621xs+ is addressed rather differently from other previous Synolgoy Rackstation releases.

The RS3621xs+ only supports the use of Synology’s own range of Hard Drive and SSD media, in the HAT5300 series and SAT5200 series respectively. This is certainly something that has raised a few eyebrows lately, as Synology has always been very open about HDD/SSD compatibility in their range. This new approach is one that is only pursued in the XS/SA/UC range starting from 2021 series (eg RS4021xs+, RS3621RPxs, etc) but means that the newer generation lacks a lot of the storage media choice of its predecessor.

You Can Read the Synology HAT5300 Hard Drive Review HERE

In Synology defence, the range of hard drives that they have produced is quite top end and although arrive at a pro-series price point, they have the architecture of enterprise-class drives (in line with Ultrastar and EXOS). At launch, these drives have arrived in a thinner range than what is presently available in the rest of the market from other hard drive manufacturers, but no doubt this will be further fleshed out as the series continues. Nevertheless, this is a distinctly aggressive move here by Synology to create more of a closed hardware ecosystem that some users who prefer a more balanced range of purchasing choices or hardware configurations may not be in favour of. Synology has stated that this system if used with unsupported drives and/or are used in unsupported configurations, will result in your warranty being unsupported also. Below is what happened when we populated the Synology RS3621xs+ with a combination of hard drives from different brands alongside the Synology hardware.

As you can see, the Synology RS3621xs+ system would only class the HAT5300 range of hard drives as compatible and applicable within the storage manager. The WD Red Pro and Western digital Ultrastar Drive media were listed as incompatible quite clearly. This is not the first time that Synology has listed hardware installed inside its system as unsupported but often users can still proceed at their own risk.

However, even when creating a simple storage pool, the system will only allow you to utilise Synology hard drives and removes all incompatible and unsupported drive media from the available list, detailing that these drives were unsupported and recommends you visit the Synology compatibility pages. However, it has to be said that Synology has still left room for a little flexibility for migrating users and even allows a small number of third-party drives to remain on the compatibility lists depending on the system.

Users who are migrating from an existing Synology NAS hardware system and want to carry over the drive media, shares, storage volumes, accounts and more are still able to migrate old non-Synology hard drives across to the new system. So at least you are not being forced to purchase a whole new system and media upon upgrading. Synology also highlights that migrating media from an existing Synology NAS to the new RS3621xs+ Rackstation will not invalidate your warranty or leave you unsupported. Although the ability to expand unsupported migrated media on the RS3621xs+ is negligible and likely still means that upon refreshing your storage media as it lessens in durability, you are still going to need to invest in Synology hard drive media.

Overall, the design of the RS3621xs+ is exactly what I would have expected from Synology and despite questions about compatible storage media, this is a largely positive and expectedly solid chassis design.

Synology RS3621xs+ Rackmount NAS Review – Ports and Connections

The rear connections featured on the Synology RS3621xs+ are a combination of impressive and safe choices. If you already own the RS3617xs+ NAS that came before this system, then there will be little or no surprises for you here. Unsurprisingly, as this system is a rack mount, ventilation with a combination of active and passive cooling are incredibly important. The rear panel features a huge arrangement of ventilation surrounding the PSUs and connections. With active cooling featured on the power supply units, but familiar active fans being moved to the middle of the chassis design (shown later).

The Synology RS3621xs+ features a 2 PSU architecture, as is the standard for enterprise-level server hardware. Each one is 500 Watt and the system runs with both active at all times. In the event that a PSU fails, the second PSU allows the system to continue running without interruption. Each PSU is covered by the systems 5-year warranty and you can even purchase a spare PSU to keep in case of emergencies. Lastly, there is of course the added benefit that you can remove that a failed PSU and install a new PSU without ever needing to power down the system, allowing active connections and shares to be uninterrupted.

Another popular feature of the RS3617xs+ predecessor that is still present here on the RS3621xs+ is the inclusion of two 10GBe Ethernet ports. Both utilising copper 10GBASE-T, this allows the system to enjoy either two individual 1000 MegaBytes connections with the local area network, enjoy failover support to ensure a redundant connection or, more popularly, can bind these connections via link aggregation and enjoy a 20 GBe bandwidth between the NAS system and all its connected users. For those that prefer the large scale application of fibre SFP+ there are numerous fibre upgrade cards available from Synology as well as some new fibre channel cards on the horizon. 12 Bays of storage populated with the Synology enterprise hard drives, Xeon processor and a decent RAID level should comfortably saturate this connection. Add to this, the ability to introduce larger and more high-performance bandwidth cards, SSD caching and numerous expansion devices and you are looking at an enormous level of performance potential later in the systems life too.

Alongside these two 10 Gigabit connections, there is a further 4x 1GB port present. These seem slightly less necessary and although one or two ports could be justified for connection to the internet or maintenance network, 4-port seems a little bit unnecessary for the overall architecture of this device. Some Pro to mid-range users have criticized Synology for continuing their implementation of 1GBe in their architecture in 2021, however, in the case of Synology RS3621xs+ I think we can forgive them a little due to the inclusion of 2x 10G, despite the likelihood of the 4 x 1Gbe ports being a tad underused here.

Another long-running staple of Synology hardware is the inclusion of USB ports that allow the system to be connected to numerous other local hardware devices. Although the compatibility of these devices on the Synology platform is a little thinner than on some other brands, overlooking KVM and general control accessories support, these ports are still perfectly usable for a myriad of external storage for backup purposes, UPS and office hardware devices and even some security utilization. They are USB 3.2 Gen 1 connections, so 5 Gigabit connectivity, but better to have them than not.

Another one of the reasons why the Synology RS3617xs+ was so popular and likely the RS3621xs+ will be too, is the expandability of this hardware solution. Arriving with 12 bays of storage by default, you can add a further 24 bays of storage with the connection of the RX1217 (up to two of them) and allow an enormous degree of storage potential, both on day 1 and day 1000 on this system. I am uncertain on how the system will react if an expansion device is populated with drives that are unsupported by the core RS3621xs+ system, but likely is soon to be detailed in the compatibility, list if not already. Generally, expandability on a solution is at its most important at the enterprise level, as these users will generate significantly more data and therefore need an ever-expanding array of storage with which to capture it long term.

As mentioned earlier, the system also features further expandability via the use of PCIe upgrade cards. Synology has a wide range of upgrade cards that span both copper and fibre connections with a recent 25GBe fibre card introduced to the upgrades listings recently. Synology RS3621xs+ arrives with two PCIe Gen 3 x8 available slots, so each card installed has a potential 8000MB/s of possible bandwidth between the card and the RS3621xs+ system. Obviously, the architecture and delivered bandwidths of every card will differ and you cannot exceed the interface or media of the card in question, but this is still a large degree of support in future for upgrade cards. There are even combination cards from Synology that factor both 10GBe and m.2 NVMe SSD bays for caching. Although it might have been nice for that SSD cache bays feature on the system by default, as found in the RS1619xs+. Still, those are great upgrade options. Let’s take a look under the bonnet!

Synology RS3621xs+ Rackmount NAS Review – Internal Hardware

The internal architecture of the RS3621xs+ has not changed wildly in terms of designing compared with that of the RS3617xs+. Arriving with the same well-ventilated layout of internal components and cooling, there is an improvement on the CPU but much else remains the same. Here is how the core components of the RS3621xs+ and RS3617xs+ compare:

So, as you can see, the general architecture has changed very little in the hardware department.

As mentioned earlier, the middle of the Synology RS3621xs+ is where the large range of active cooling is found. On the side of the RS3621xs+, we find a button that when pushed, opens the door panel to reveal four block fans. Each van can be removed easily for cleaning and general maintenance as needed, and when the system is in operation, all four fans blow exceptionally hard to maintain cool internal temperatures and ensure the efficient running of the CPU, memory, network cards and more across the internal PCBs.

Removing the lid of the Synology RS3621xs+ is quite straightforward and doing so reveals a nice clear area of space, as well as an area of directional air control across the CPU and it’s large heatsink.

This plastic panel channels the airflow through the bulk of the cooling fans, delivering it directly over the processor and that large heatsink. The CPU inside the RS3621xs+ is an 8 core Xeon processor, D-1541 that has a 2.1Ghz clock speed that can be burst to 2.7Ghz and among one of the most powerful in the Synology line up, if not the most recent. Arriving with a score on the CPU benchmark of over 9500, this is still a great data center processor for handling thousands of actions at any given time.

This processor brings several additional advantages to this server system, both inside and outside of Synology DSM. On the Synology first-party side, it allows the full complement of Synology software and services to be available straight away, as well as largely unparallel simultaneous usage at any given time from hundreds of active users or applications. In terms of third-party hardware, it allows a huge amount of performance to be possible via the myriad of network ports and upgrade cards available. However, it is worth highlighting that this processor is a 2016/17 release and although generally, we expect the processes in a NAS system to feature an element of efficiency and durability not found in PC architecture, some might find this processor the tiniest bit underwhelming for the price tag. Especially given the quality of processors released last year in the SA and FS series of devices, such as the 12-core Xeon found in the SA3600, or the Intel Xeon Silver 4110 2x 8-Core CPU in the FS6400.

Alongside this 8-core processor, the system also arrives with 8GB of DDR4 ECC UDIMM memory. Synology has been in the habit of introducing ECC memory in all of their SMB and enterprise products in the last year and that is always going to be appealing to a number of data-sensitive buyers who understand that data loss can happen from the tiniest of bit failures, that can snowball into something much worse. Error code correcting memory ultimately compares data that passes through it at the beginning and end and in the event that change or damage is identified, the file is then healed automatically to the previous state. These checks are done constantly as the system processes data and is a nice extra touch from Synology to include as standard (with further increases with BTRFS inside too). The memory on the RS3621xs+ can be upgraded to a maximum 64GB across for available slots. Which on the one hand seems like a lot of memory and at the same time seems less than I would have expected from a system of this calibre with that processor. Especially given that Intel rate this processor to support a maximum 128GB of memory, depending on the modules used. Perhaps this is a limitation of ECC memory or a limitation based on Synology not providing 32GB modules, still, nevertheless, it is a solid CPU and memory combination to be utilising inside the RS3621xs+ on day one.

Overall, the arrangement of storage media and how it is delivered to the mainboard is clean and efficient, with numerous internal SAS cabling accompanied by a dedicated network controller for that 10G connection. During our testing, we were able to comfortably accommodate four Windows 10 VM on the default hardware are using Synology virtual machine manager, and could likely host more as a target and with VMware support.

Synology RS3621xs+ Rackmount NAS Review – Software

You will be pleased to know that the upgrades in the Synology RS3621xs+ NAS of that 8 Core Xeon processor, over that of the Intel Atom, mean that the entire Synology application range is available to you and in all cases, you will get faster performance and larger simultaneous access than previously. The Synology range of NAS devices all features the same software, in DSM 6.2 (DSM 7 beta revealed and available to test NOW). What separates them is the extent to which it can run the software, both in terms of which applications and to what extent. This is often governed by the memory and CPU inside and the RS3621xs+ NAS is no exception. If you currently own an RS3617xs+ NAS from Synology, then chances are that the Synology RS3621xs+ NAS will have little or nothing that you have not seen before. Likewise, the 4-Bay 1U RS1619xs+ (which features a quad-core CPU in the Intel Xeon family and M.2 NVMe SSD Bays), might mean for some that in terms of performance, this quad-core processor in the RS3621xs+ does not present a massive upgrade to you. However, for those looking for a robust storage NAS with RAID coverage and internal hardware that will stand the test of time, the newer NAS represents a great solid block for your network-attached storage system and in a straight comparison, wins in almost every way against most systems in their portfolio. The RS3621xs+ NAS supports a multitude of first-party applications and third-party apps for home and business use, such as:

Alternatively, you can test Synology DSM 7.0 Beta in an online demo by visiting below:

A software review (and comparisons) of the DSM 6.2 platform on the RS3621xs+ NAS is currently in process and I hope to have this to you here on the blog very soon or on the YouTube channel in due course. Stay tuned.

Synology RS3621xs+ Rackmount NAS Review – Conclusion

The RS3621xs+ is another solid example of what Synology provide too business users with their solutions. Although not a great deal of hardware evolution has happened in the 3 to 4 years since its predecessor, this is a system that is able to take advantage of a large number of improvements in the Synology software in 2021. There is still a feeling of safety from the brand in how they designed this system within their overall portfolio of solutions, that might make you feel that its wings may have been intentionally clipped in places, but this is still a fantastic example of the Synology XS series. Likewise, if you are happy to purchase first-party drives in line with the Synology compatibility list, there is little reason for enterprise users not to purchase the RS3621xs+ for their business in 2021.

The Synology RS3621xs+ Rackstation is another solid and reliable piece of kit from one of the biggest brands in NAS and although I did not expect it to disappoint, it is still arguably the teeniest bit safe as an upgrade over its predecessor. An improved CPU, improvements in quality and quantity of memory and the ways in which the system can be upgraded are always welcome. But if you already own the Synology RS3617xs+ that came before it, there are not going to be enormous improvements here that warrant an expensive upgrade. Additionally, the policy of the newest generation with its rather strict policy on compatible hard drive media might not be for everyone and being more desirable to those more committed to the Synology ecosystem. An excellent piece of hardware that nevertheless manages to play it safe and be controversial at the same time.

The Synology RSx23 and DSx23 Range are shaping up to be one of the busiest ranges from Synology for quite a few years, with recent information passed to me on a new 12-Bay expandable Rackstation solution, the Synology RS2423+ NAS. This new system information arrives alongside those of quite a large number of new smaller-scale systems that are planned for release towards the end of 2022 and the start of 2023, but this rackmount NAS is a new entry into a popular SMB (Small/Medium Business) tier of the brand’s portfolio and is the planned follow up to the RS2421+/RS2421RP+ that was released in March 2021, with seemingly very similar architecture planned. Very little is known about this device right now and I would certainly peg it for a Q1 2023 (Jan-March) release, as this is typically the window for this kind of solution, but lets discuss the new RS2423+/RS2423RP+ and everything we know, as well as a few predictions.

What do we know about the Synology RS2423+ and RS2423RP+ NAS?

Information on the Synology RS2423+ and RS2423RP+ Rackstation NAS arrived with me from a trusted site and references/links to an official Synology source, so I am 99.9% sure this system is real/legit. There was further information relating to a new CPU, but as this was an element of the information is unverifiable, I won’t share it here (but as soon s it IS, I will add it as an update to the article above). However, what we do know about this system is the following;

• The Synology RS2423+ is a 12-Bay Rackstation NAS that is also available in an RP (Redundant PSU) version, such like it’s predecessor the RS2421+/RS2421RP+
• These new Rackstation systems will use a new /updated Rackstation Expansion chassis, the Synology R1223RP to add an additional 12-Bays of Storage to your primary Synology Rackmount NAS
• The CPU and Memory of the RS2423+ is TBC, but it IS confirmed that the rackmount will be using traditional PCIe Upgrade methods over PCIe 3 (supporting the E10M20-T1, M2D20, E10G18-T1, E10G21-F2, etc) and not the smaller form factor upgrades such as the E10G22-T1-mini
• HDD Support is unconfirmed, but expect similar to the RS822+/RS822RP+
• Expect a 2U height Rackmount at 88 mm x 482 mm x 552 mm size for the regular 350W PSU RS2423+ and 88 mm x 482 mm x 578 mm for the RS2423RP+ 250W dual PSU version
• No native/on-board m.2 NVMe SSD Bays

As it stands, that is all that I can confirm at this time. I will update this article accordingly as further information arrives and/or is confirmed

Unfortunately, at this time, this is pretty much everything that we have to go on right now for this new Synology rackmount. The big question is likely going to be about the CPU. The RS2421+/RS2421RP+ that arrived midday through 2021 arrived with the AMD Ryzen V1500B Quad Core Processor and 4GB of ECC DDR4 Memory. Over the last two years, Synology has been slowly upgrading the SMB/Mid-sized business solutions that formally featured the Intel C3538 Atom with this newer, more efficient and powerful embedded Ryzen V1000 CPU. So, right now it is not known what the next choice of CPU for this product family will be. The RS422+ featured an AMD embedded Ryzen R1600 Dual Core processor, but this seems to a tiny bit of a step back when compared again this scale of storage, the product family and especially when you line it up with the RS822+ in between. Wee will have to wait and see how Synology proceeds on this one. With regard to connectivity, I do not think we are going to see anything greater than multiple 1GbE ports by default on this system. Never say never etc, but given that I understand this system will still keep its PCIe upgradability, then chances are that Synology will settle on this system being 10/25G upgradeable via their range of supported upgrade cards, rather than have greater than gigabit connectivity by default.

When Do We Think the Synology RS2423+ NAS Will Be Released?

Unfortunately, ZERO information is available right now on the eventual release and availability of the Synology RS2423+ and RS2423RP+. As mentioned earlier, this scale and type of solution tends to arrive in the Q1/Q2 period of the year usually, which would put the release of the RS2423+ much further into 2023. We will update this page with further information on this NAS as it arrives, so if you want to be kept aware of it, chuck your email in the email change notifications box below (you won’t be creating an account or anything). Stay tuned!

If you have been keenly following Synology hardware and software releases so far in 2022, then I think it would be fair to say that they have been rather business-focused. With many of us anticipating the reveal of a new plus series 22′ 2/4 Bay in their lineup, we have all rather been caught off guard with the number of Small/Medium-Business to Enterprise solutions revealed so far. And today we want to discuss another entry into that tier of the brand’s portfolio, with the Synology RS822+/RS822RP+ Rackstation NAS – a follow up to the RS820+/RS820RP+ NAS revealed back in 2019, that is going to arrive with a familiar range of hardware choices from Synology, but in this tight 1U expandable server. Arriving on the scene oddly close to the similar RS422+ NAS, the new RS822+ and RS822RP+ (same NAS, but redundant secondary PSU on board) is a much more expandable and upgradable solution in a number of ways and follows on from previous entries by Synology in this product line. Let’s take a closer look at the hardware on offer, how it will impact on DSM 7.1 performance and whether this system will deserve your data in 2022.

Hardware Specifications of the Synology RS822+ and RS822RP+ Rackmount NAS

Much like a number of PLUS series in the Synology portfolio that are geared toward small-medium business (SMB) users, the 4 Bay RS822+/RS822RP+ arrives with the AMD Embedded Ryzen V1500B quad-core processor that first debuted on the DS1621+ and DS1821+, so Synology has had plenty of time with this CPU to get the most out of it for DSM. Whereas the RS422+ NAS first revealed here 2 months ago which arrived with the AMD Ryzen R1600, so it will be interesting to see how these two processors will compare later down the line when they are both on the market. The system also arrives with a slightly underwhelming 2GB of memory, but this can be upgraded to an impressive 32GB of memory. Additionally, this memory is ECC (error-correcting code), so high volume and frequency transfers will have that additional checksum in the background to check data write as it passes through and repair the files that aren’t up to snuff! Oddly, this is another system that does not arrive with M.2 NVMe SSD bays, despite Synology highlighting the importance of caching on business transfers – especially odd when the 6/8 Bay systems with the same CPU/Memory architecture arrive with the 2 slots by default. You can add this, as well as network upgrades, via the available PCIe Gen 3 x8 upgrade slot on the rear though, so it is not the end of the world. Finally, we can see that the RS822+/RS822RP+ arrives with 4 LAN/Ethernet ports which are 1GbE each. Despite the advantages of this system supporting LAG/Port trunking to maximize that bandwidth, it is still slightly puzzling that Synology continues with implementing gigabit ethernet on their solutions in 2022. 2.5GbE and 10GbE are hardly mainstream (and the latter clearly would incur additional cost), but with most looking at a system like this to last them a good 3-5 years at least, that would have been a nice bit of future-proofing in terms of base-level connectivity and not partially limited behind an upgrade hurdle. Overall, the hardware here still results in a solid 4 Bay 1U NAS, but not a huge jump up from the RS820+/RS820RP+ outside of that CPU. Below are further specifications:

How does the Synology RS822+/RS822RP+ Compare with the Synology RS820+/RS822RP+ NAS?

Perhaps you have been considering the Synology RS820+/RS820RP+ already, considering upgrading from it or had already been holding out to see if the brand would introduce a follow-up in 2022? Whatever your reason, comparing the Synology RS820+ and RS822+ Rackstation NAS is not taxing. The new Ryzen V1500B CPU in the RS822+/RS822RP+ NAS being with it a much more proficient and capable system overall. Along with this, it allows the newer 2022 unit to support more memory (thanks to the system having 2 slots, not 1), ECC Memory included, faster overall transfers and ultimately means that you are going to get a  great deal more efficiency out of DSM’s day to day operations. So, if you want more hardware available for larger ranges of connected users and tasks, the RS822+/RS822RP+ has this advantage straight off the bat. After that, things are quite similar – both have a PCIe 3×8 slot, both support the RX418 expansion, both have 4x 1GbE LAN and USB 3.2 Gen 1 and both have a redundant PSU version available. Still, that greater performing CPU is going to seal the deal for many. Below is how they compare on the specifications table:

Hard Drive & SSD Compatibility on the Synology RS822+/RS822RP+ NAS?

It’s an important question for many users! Since Synology changed their support and compatibility position on a number of high-end business solutions in 2022 to change their supported HDD/SSD to feature only their own media, many have been concerned that this was a trend that would continue in other releases. I am pleased to confirm that this is not the case with the RS822+/RS822RP+ and this new 1U 4-Bay Rackmount NAS has a considerable number of 3rd party HDD vendors listed on the compatibility pages. It is still not exactly exhaustive and the available list of drives is not as wide in brand and capacity as we have seen on older Synology NAS releases, but it good to see that this system is not going to have the tighter compatibility on media that the likes of the DS3622xs+ and DS2422+ NAS arrived with at launch.

Software Specifications of the Synology RS822+/RS822RP+ NAS?

As the RS822+/RS822RP+ NAS system arrives with a familiar Ryzen V1500B and DDR4 ECC Memory architecture that was seen on the DS1821+ and DS1621+, we can already ascertain that its performance with DSM 7.0/7.1 is going to be very good. This is not a hardware architecture that is going to lend itself very well to high graphically demanding tasks (so 4K Multimedia is off the table) but these specifications will still run the entirety of the Synology first-party applications available for business (backups, the collaboration suite, VMs, Surveillance, cloud synchronization, etc). Here is a breakdown of what the RS822+/RS822RP+ Rackstation supports and to what extent:

Any Confirmation on the Price and Release of the Synology RS822+ and RS822RP+ NAS?

Right now we are still awaiting confirmation on the pricing and release date on the RS822+/RS822RP+ Rackstation NAS to be confirmed by Synology. However, it has already appeared online in the east of the globe and that likely means that we will see it’s release before the end of July at the latest. Add to this that the model name has ’22 in it and that means that Synology will likely want this model released before August (typically the tipping point for when model IDs change to the follow-up year, 22 > 23). Pricing will almost certainly be near enough identical to the price of the RS820+/RS820RP, at around the £800-900 – $900-950 o- €850-950 mark (your region and local TAX depending) but that is still unconfirmed. Stay tuned for more updates on this NAS by following me and Eddie on NASCompares.
