Compact 1U rackmount storage

The Synology RS422+ is a 4-bay rackmount NAS delivered fully assembled with 64 TB of Synology Enterprise drives. An AMD Ryzen processor and 2 GB of memory run DiskStation Manager for file sharing, synchronisation and backup. Small businesses and homelab owners gain a ready-to-rack platform without extra build steps.

Space-saving chassis and connectivity

The 1U form factor fits 2-post or wall-mount racks where full-depth cabinets are unavailable. Dual 1 GbE RJ-45 ports support link aggregation and failover for resilient throughput. A single USB 3.2 Gen 1 port allows direct attachment of external drives or peripherals. Front-access drive bays simplify swap-outs without sliding the unit out.

Expands from basic file servers

Replaces standalone USB drives or entry-level desktop NAS units that lack rack mounting and redundant networking. The jump is worthwhile when centralized management, snapshot-based backup and multi-site sync become daily requirements. Buyers needing more than four drive bays or 10 GbE connectivity should evaluate larger rackmount models.

Questions about this item

What does the dual 1GbE RJ-45 interface cap at in practice?

The two 1GbE ports support Link Aggregation and Failover, giving up to 2Gbps combined throughput or automatic redundancy if one link fails.

What rack space and depth does the 1U RS422+ need to mount?

It occupies 1U (44 mm height), 478 mm width and 327.5 mm depth, fitting a standard 2-post or wall-mount rack without rails.

How are the four 16TB enterprise drives installed, and what step is often missed?

The unit arrives fully assembled and tested with all four drives pre-installed; the only step is racking it, connecting power and network, then running the DSM setup wizard.
