Synology RS422+ Rackstation NAS Revealed

Synology RS422+ NAS Drive Revealed

As we slowly learn more about what Synology has planned for 2022 in their hardware and software solutions, one thing that is becoming increasingly clear is that the latest refresh of some of their staple hardware series has made some big changes in scalability. The latest NAS to be revealed for Synology 2022 is the RS422+ 4-Bay Rackstation, a similar NAS to the current RS820+, but with some key differences in its internal AND external architecture. Synology has featured one or two different SMB fully-featured 1U rackmounts in their portfolio over the years and this 40cm deep rackstation features several of the specifications of the Synology DS1522+ NAS we revealed recently, so let’s breakdown everything we know about the Synology RS422+ NAS so far.


Further information on the RS422+ Rackstation NAS has become available that details a lot more information about the specifications of the system, as well as confirmation regarding hard drive and SSD compatibility on this system when released. I have also added further information regarding the E10G22-T1-Mini adapter for this system.

Synology RS422+ Rackstation NAS Hardware Specifications

The new Synology RS422+ rackstation NAS arrives with a number or architectural choices that suggest that the system may have a slightly more value/affordable angle around its design over that of the RS820+. It arrives with an embedded AMD Ryzen CPU inside, much like the previous 4 bay rackmount in the 20+ series. However, unlike the quad-core 2.1Ghz Ryzen V1500B in the last generation, this new NAS features a dual-core 2.6Ghz-3.1Ghz Ryzen R1600 embedded Ryzen processor. Now, this IS a more proficient CPU, albeit a shame that it is 2 Cores/4 threads. Also, memory at this time has been stated as 2GB of DDR4 ECC. However, this memory cannot be upgraded/increased and 2 gigabytes is the most you will ever be able to utilize’. Additionally, the RS4422+ does not arrive with the m.2 NVMe SSD slots that some of the Diskstaiton solutions arrive with.

However, the thing that interests me the MOST about this system is a neat little extra slot that the RS422+ arrives with on the rear. Alongside the 2x ethernet ports (1GbE – which really surprised me! With so many of us banking on 2.5GbE, as well as only featuring 2x) there is a small slot that allows you to install an optional and proprietary E10G22-T1-Mini 10GbE Module. This means that this 4-bay system can have 10GbE connectivity added down the line. Now, I am not completely in love with the idea of this connection being added via a proprietary add on that is likely physically specific to Synology NAS, however, there is every chance that this is the case due to reasons of physical space on the system and PCI lane limitations. A couple of months ago on the Data News of the Week series on YouTube, I discussed an m.2 to 10GbE adapter that had been developed (with a dedicated controller from Realtek) that allows 10G to be connected via a simple 10G port. This could potentially be the same, but we are still awaiting confirmation on that one. Here are the rest of the specifications we know so far:

Regarding hard drive and SSD compatibility on the Synology RS422+ NAS, Synology have detailed Seagate and Toshiba (as well as their own HDD/SSDs too of course) are compatible with this NAS. This will come as good news for anyone that was concerned that Synology might have been extending their position currently on enterprise 2022 released hardware towards supporting and recommending other HDD models towards the Home, Prosumer and SMB tiers of their portfolio.

Synology RS422+ Rackstation NAS Software Support

In terms of software and DSM 7.1, the Synology RS422+ NAS supports pretty much all the of the first party applications available from the brand, as well as all the storage services that the brand is well known for. The 2GB of memory supported by this system does mean that some applications are a little more ‘lower glass ceiling’ in their full utilization, but for a small business that is just looking for an easy to deploy storage server for their data, backups, surveillance and a couple of lite virtual deployed clients, the RS422+ has both the hardware and the software to get that one Here is the full breakdown of the software support of the RS422+ rackstation.

Synology RS422+ NAS – Release Date and Price

Although we have lots of information on the hardware specifications of the Synology RS422+ NAS and details on the design, when it comes to release details and possible pricing, there is little to no information at the time of writing. Synology has always tried to match the price of the predecessor unit in a series in their portfolio (maybe increasing 2-3% on the RRP factoring in inflation, component price increases. However, the RS422+ is a different beast to the RS820+ and RS819 before it, as well as lacking the storage expandability of those, so that makes the price a great deal harder to estimate! Regarding release dates, as this system has the ’22 model ID, that tends to mean that the system will arrive before the end of July/August at the very latest. That said, I think this system will drop a good while before that and I assume somewhere in the 2nd half of Q2 (May/June). There are a few more Synology bits to discuss coming shortly, so do remember to subscribe or bookmark as more new information is published. Cheers for reading and have a lovely week!

      13 thoughts on “Synology RS422+ Rackstation NAS Revealed

      1. Hi gang! More information has arrived on the RS422+, which includes concrete specification information (that memory quantity), as well as improved images and much more information on the 10GbE upgrade port on this system. I have updated the news article with info and images, so you can find it here –

      2. This is exactly what I’m wanting. In my world, it’s about a rackmount server. The HD capacity is already over the top for our needs (massive sites won’t hit 1TB, I just hope the Ram is upgradable. We basically use it as a MariaDB server. Simple to set up with great reliability.

      3. This seems to be something that manufacturers are doing more and more, introducing a product which doesn’t seem to satisfy any realistic user requirement but just sits in the lineup to support the higher price of the next unit up that does provide what most people would want.

      4. Synology refused to provide support for my 21+ model (Ryzen-based) as I was using WD SSDs in it and only their own brand are approved. No warnings at all on DSM6.2 (as was current at time of purchase) but appeared when I moved to DSM7. When only 8 months old it the NAS produced a random set of errors and basic testing by me showed a power issue somewhere. Syno took my logs and my diagnostics but ignored everything apart from the log showing WD drives being used. Further support stopped-dead at that point. Effectively I was on my own and a multi-year warranty vanished.  
        Syno recommended fitting their own SSDs (at several thousand £s) but acknowledged that they were not actually in stock anywhere, even if I was rich enough to buy their ridiculous priced rebadged drives for a simple consumer Linux-based NAS.
        Anyway, I got the o’scope out and probed away until I found power transients on the PCIe bus and eventually traced the issue back to the Synology network card, which I replaced at my own cost to give me a healthy system again. Synology are no longer honest brokers and will take any non-branded components as I reason to suspend tech support and deny any warranty action based on their ‘belief’ that any and all faults are caused by using components made by major and respected OEMs.

        Qnap seems full of holes so TruneNAS for me when I need to refresh any of my 4 Synology NASes. Any further failures will see me filing my £50 with the UK Small Claims Court as arguing with Synology is pointless without the independant eyes of a judge.
        [For those in the UK fearful of using the Small Claims Court it is dead easy. Simple form, provide your evidence and typically no need to ever attend court, let alone hire a solicitor. The awards are typically the price you paid, plus expenses and a small amount of compensation (usually just £50 or so, this is not the US system!) but if found against the defendant may find themselves under additional scrutiny from more major regulatory bodies.

      5. Do you think the RS1619xs+ is still a viable option compared to the current disappointing 1U 4-bay and perhaps 2U 8-bay options? My concern is if Synology will continue to support the RS1619xs+ beyond the DSM 7.X software versions.

      6. Damn. I hope they don’t change every nas to an AMD CPU. I was really looking forward to replace my current ds718+.

        I use it mainly for plex, so maybe I need to take a look at an Intel nuc

      7. Uploaded to Reddit, this really hurts the viability of the rest of the 2022 Desktop models. After the incredible consumer electronics spending the last 2 years in the face of pandemic, crypto mining, and supply shortage. Consumers were buying premium computer equipment, why would Synology not take a big swing this year, QNAP keeps pulling away in hardware. Can DSM 7.1 keep enough loyal consumers? This is like watching a championship sports team fall apart a few years later. ????????‍♂️
