Synology DiskStation DS2422+ 12-Bay NAS review

A twelve-bay desktop platform for planned growth

The DiskStation DS2422+ is a tower-style NAS with twelve native drive positions, aimed by Synology at small and medium businesses with large shared datasets, backup jobs and multi-user storage. The chassis measures 270 × 300 × 340 mm and weighs 9.5 kg before drives. Allow room for ventilation, cables and tray access.

All twelve bays accept 3.5-inch SATA hard drives or 2.5-inch SATA hard drives and SSDs, subject to the current compatibility list. The base package lists one AC cord and two RJ-45 cables but no data drives. One separately sold DX1222 shelf can raise the total to 24; that is not the chassis's native bay count and the expansion is not included.

Choose a layout before filling all twelve trays

The supported storage list includes SHR, Basic, JBOD, RAID 0, RAID 1, RAID 5, RAID 6 and RAID 10. Two compatible drives can form a RAID 1 mirror, but pool expansion or drive replacement must follow the exact layout’s instructions. Larger arrays may need more drives for the intended redundancy and can involve longer rebuild windows; choose a layout around failure tolerance and restoration, not bay count alone.

Internal volumes can use Btrfs or ext4; the listed 108 TB maximum is a system ceiling, not a usable-capacity forecast. Drive sizes, RAID and filesystem overhead determine file space. Check exact drive models on the current DS2422+ compatibility list.

Four built-in gigabit ports, with a separate upgrade route

The base machine has four RJ-45 1GbE ports, two USB 3.2 Gen 1 ports and one PCIe Gen3 x8 slot running at x4 link. The Ethernet specification matters: none of the four built-in ports is 10GbE. Synology lists optional 10GbE and 25GbE network cards, and a compatible E10M20-T1 adapter can combine 10GbE with M.2 NVMe cache. Those parts are not included in the standard package. A faster NIC also needs a compatible switch or direct connection, client adapter and cabling; do not treat a NIC label or four aggregated gigabit ports as a promise of a single-client transfer rate.

No M.2 positions are integrated into the twelve SATA bays. NVMe cache requires a separate compatible adapter and drives; a SATA SSD can instead occupy a native bay. If both faster networking and cache matter, check a supported combination card for the single PCIe slot.

Memory and workload shape

The DS2422+ uses an AMD Ryzen V1500B quad-core processor and ships with 4 GB of DDR4 ECC SODIMM memory; Synology lists two slots and a 32 GB maximum, subject to its module guidance. It supports shared storage, backup, snapshots, surveillance and virtualization packages, but workload, pool design and network path still determine fit. Some advanced features or additional camera use require separate licenses.

Synology publishes sequential performance figures from its internal test environment. Its product page specifically notes that performance testing used 10GbE NICs, while the standard unit has only 1GbE ports. Those figures are context for a configured test, not results I measured or a prediction for a diskless configuration, a gigabit client or a mixed file workload. The current product specification also lists a 550-watt supply and one power inlet; it is not a dual-power-supply RackStation design. If redundant facility power is important, include the UPS and electrical path in the system design.

How the DS2422+ differs from a nearby 12-bay tower

The DS3622xs+ shares a 12-bay desktop form factor but is a materially different configuration. Synology’s current comparison lists the DS3622xs+ with six CPU cores, two built-in 10GbE ports, three additional gigabit ports, five years of warranty and support for up to 36 bays. The DS2422+ instead has four built-in gigabit ports, a four-core Ryzen processor, a 24-bay expansion ceiling and a three-year hardware warranty. These are source-listed differences, not a price or performance ranking. If built-in 10GbE is essential, the DS3622xs+ is the more direct port match; if a one-card 10/25GbE upgrade and twelve native bays meet the requirement, the DS2422+ remains a documented alternative.

Purchase and installation checks

Verify the exact DS2422+ package, seller warranty and drive model codes. Plan the RAID/SHR layout and a separate backup destination. If you need more than gigabit networking, add a compatible NIC and a matching switch/client path. Confirm the DX1222 shelf model and budget for its separate drives. The 9.5 kg chassis weighs more once populated, so use suitable support and ventilation.

Assessment

DS2422+ makes sense when twelve native SATA bays, ECC memory, business-oriented DSM services and a documented path to 24 bays are more important than built-in multigig Ethernet. It is a large, drive-dependent storage platform, not an all-in-one priced bundle: drives, DX1222, NICs and NVMe cache accessories are separate. A two-drive mirror can help preserve availability through one member-drive failure, but it cannot replace a versioned backup stored somewhere else. Synology’s U.S. Product Support Status record observed October 29, 2026 lists the model as Generally Available with Full DSM updates, Full Technical Support and a three-year warranty; that does not establish a retailer’s current stock or exact package.
