Synology RS822+​/​RS822RP+4-bay 1U rackmount NAS

Synology RS822+ and RS822RP+ Rackstation NAS Unveiled

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.

      20 thoughts on “Synology RS822+​/​RS822RP+4-bay 1U rackmount NAS

      1. my boss just bought this one for our new server rack. I am used that the ears of a rack are out of metal. these ones are plastic. can they be mounted to a rack holding this on the ears or do the need some backup with L-profiles?

      2. I have hard times believing that Synology is still pushing 1CbE. By now they should be having 10GbE on all their boxes and making sure that it is backwards compatible. As to memory the 32 GB Max is adequate. It would be better if it were expandable all the way to 64 Bg but let’s not split hairs here. I wish you had discussed the Surveillance software on this box. I think that the QNAP TS 435XeU may be a better option for me. It is more flexible, and it seems to potentially have a longer life due to its expandability. I think Synology missed the boat here.

      3. I have been using the RS815+ for a very enthusiastic home automation system, running in several docker containers (MQTT, SmartHomeNG, Unifi Controller, MariaDB, InfluxDB, smartVISU, etc). The database with sensor data had been growing to 8gb over the years, making queries for historic data very slow. Now with the upgrade to the RS822+ with 16gb RAM extension, it works like a charm. And after 7 years of using the RS815+ I think an update was fine.

      4. This is the exact server I have been wanting… CPU that will run well.. not an atom and upgradeable ram. Wish they had of made it in the half depth of the rs422. It would have been my one and only standard for installations. We don’t need a lot… Atom was just a little too small and xeon was a lot too much for most sites… Now if they just have ram available…

      5. It would be ok if the specs were improved for the money you get very little you’re paying for all the programs most people never use and no matter what you do it’s the same chip inside i think nas are way over priced and should be cheaper

      6. Sorry but im a home user and i dont need 2,5 Gb Port. I need only rack mount NAS. The most home user have only 1Gb network. And if you are a pro user or bussines user you have the option with this 10 Gb or 4x1Gb, but i think this NAS ist more for home or realy small business user. The same with the 422.

      7. As much as Synology would like to think they are  – they are not. So you need a managed switch to get the best performance out of it. Ram should be 4GB as a minimum these days and NICs at least 2.5G capable.

      8. These guys are really following apple, by the time you upgrade the memory and the network connection the price of the machine is already twice the initial.
