Synology Unveils Massive DS2422+ NAS Server, New DX1222 Expansion Unit

Share what you're reading!

If for some reason, you find the six-bay DS1621+, which I called the “ultimate home NAS server of 2021”, not spacious enough, there’s now another option. Indeed, today, Synology unveiled the DiskStation DS2422+.

Synology DS2422+: A new NAS of an all-new expansion solution

As the name suggests, this is the 2022 high-end model year NAS server for home and small businesses that can handle up o 24 internal drives.

By itself, the DS2422+ can host up to 12 internal drives, twice that of the DS1621, in its two columns of the horizontal drive bays. And this is where it gets exciting: the new server now supports a new expansion unit with a much faster connection speed.

Indeed, on the back of the DS2422+, you’ll find an all-new Mini-SAS HD port that’s capable of delivering up to 24Gbps in throughput. This port is designed to work with a new expansion unit Synology also announced today, the 12-bay DX1222.

For many years, Synology’s Plus NAS servers host storage expansion via a much slower eSATA port standard that caps at just 5Gbps, which is the bottleneck between the main server and an existing DX517 unit.

The DS2422+ together with the DX1222 rings in a new era where you can expand storage quickly without compromising performance at all. It’s safe to say, future Plus NAS servers will also support this expansion unit.

Familiar specs

However, the most exciting part about the new server is probably that it shares almost the same hardware specs as the DS1621+, the first Synology NAS that runs on an AMD CPU.

Indeed, the new server uses the same AMD Ryzen V1500B quad-core 2.2 GHz process and 4GB of stock memory (upgradable to 32GB).

On top of that, it also has four regular Gigabit ports plus a PCIe add-on slot to host an expansion card to add 10Gbps network capability or NVMe caching.

It’s worth noting, though, that while the DS1621+ comes with two built-in M.2 NVMe slots to host two NVMe SSD right away, the DS2422+ doesn’t—you need to use the expansion slot for that.

However, considering caching is generally unnecessary for most home and SMB applications, chances are you’ll find the new 12-bay server’s extra drive bays a more valuable trade-off.

DSM 7 out of the box

The DS2422+ is the first NAS server from Synology to run its latest operating system, the DSM 7, right out of the box. That means you won’t be able to use legacy DSM 6-compatible with it.

But that’s not necessarily a bad thing. I’ve been using DSM 7 for a couple of months now and found it quite an excellent OS—more on DSM 7 in this post—with a ton of useful built-in free apps.

Synology DS2422Back
Here’s the Synology DS2422+’s back. Note the all-new Mini-SAS HD port to host a DX1222 expansion unit.


Synology says the new DiskStation DS2422+ and DX1222 expansion units are available today, though the company didn’t reveal how much they cost.

In any case, if you choose to use the new DS2422+ server as a single unit without an expansion, chances are it’ll give you the same experience as the DS1621+.

That said, check out my in-depth review of the DS1621+ below to have some idea of how well the new 12-bay server will do for your case. My take is it’s going to be worth the investment.

Design and Setup
8.5 out of 10
9 out of 10


Powerful AMD CPU delivers fast and reliable performance

Robust DiskStation Operating System with tons of useful home and business applications, including Virtual Machines

Straightforward and consistent setup, upgrade, and management

Built-in M.2 NVMe slots

Lots of network storage options

Quiet operator


Expensive RAM upgrade

No built-in 10Gbps port (adapter required)

Only two camera licenses included

If you really want to get to the next level of performance, though, Synology also announced the much more expensive DS3622xs+ for large businesses or professionals, which is a similar upgrade to the DS1621xs+. Basically, it’s an Intel Xeon-based version of the DS2422+ that can host two DX1222 expansion units.
