Synology RS422+ officially released

RackStation RS422+ NAS Officially released

Milton Keynes, United Kingdom – 1st June, 2022—Synology Inc. is pleased to announce the latest addition to the RackStation+ lineup, the Synology RackStation RS422+, a compact and affordable all-in-one solution for edge server applications, small businesses, and home lab owners looking to meet their daily data management, sharing, synchronization, and backup needs. 

“The RS422+ is an enticing option for small businesses and home lab owners that are looking for a compact and reliable backup or edge storage solution at a cost-effective price,” said Michael Wang, Product Manager at Synology Inc. “This expansion in our RackStation series strengthens our rackmount offerings, providing our customers additional variety so they can best find the most suitable Synology solution for their specific needs.”

Providing big value in a small footprint

Built to support small deployments, the RS422+ has a depth of just 327.5 mm (~12.89 in) with server handles installed. Its compact 1U chassis fits perfectly in a 2-post or wall mount rack. The dependable performance of the RS422+ along with its compact size, power efficiency, and support for the Btrfs file system, which allows for snapshots and self healing of data, makes it a reliable solution suitable for edge server applications. 

Furthermore, dual 1GbE ports with support for link aggregation makes the attractively-priced RS422+ ideal for use as a mail, surveillance, or directory server. Its built-in high availability feature allows it to be clustered with another RS422+ to form a high-availability cluster, thus ensuring maximum uptime for crucial services. For customers looking to expand their network speeds, upgrading is a breeze thanks to support for 10GbE Ethernet plug-n-play upgrade modules.

Take advantage of the cloud with Hybrid Share 

Get the best of both worlds when combining RS422+ with C2 Storage. Hybrid Share combines the local performance of Synology NAS with the scalability of C2 Storage. Large sets of data are kept in the cloud while requested data is streamed to branch offices using the vast bandwidth of a data center. Frequently used data is retained in a cache on local NAS for fast, low-latency access. Furthermore, data security is enhanced as data transfer from NAS to C2 Cloud is end-to-end encrypted.

      13 thoughts on “Synology RS422+ officially released

      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. ????????‍♂️
