Compact 1U rackmount NAS with 64 TB storage

The Synology RS422+ is a four-bay rackmount NAS delivered fully assembled with four 16 TB enterprise-class drives for 64 TB of raw capacity. An AMD Ryzen processor and 2 GB of memory run Synology DiskStation Manager for file sharing, synchronisation and backup tasks. Dual 1 GbE ports and an included E10G22-T1-Mini 10 GbE adapter provide flexible connectivity for small businesses and homelab owners.

Sustained workloads on Ryzen power

The AMD Ryzen CPU handles continuous file transfers, backup jobs and multi-user access without throttling, while the four enterprise-grade 16 TB drives are rated for 24/7 operation. Link aggregation on the dual 1 GbE ports balances traffic during prolonged sessions, and the 10 GbE adapter maintains high throughput for demanding workloads such as virtualisation storage or media editing. Operating temperatures from 0 °C to 35 °C ensure stability in typical rack environments.

Replaces tower NAS or direct-attached storage

This unit upgrades from standalone desktop NAS boxes or external DAS arrays that lack rackmount density, redundant networking or enterprise-class drives. The jump is worth it when you need 1U rack integration, combined 1 GbE and 10 GbE links, and drives built for constant duty cycles. Buyers who require more than four drive bays, GPU transcoding or larger memory configurations should look elsewhere.

Questions about this item

How loud and hot does this RS422+ get when it runs 24/7 with four 16TB enterprise drives?

The chassis is rated for 0°C to 35°C ambient temperature and 5-95% humidity. It draws power from 100-240 VAC at 50/60Hz. No fan-decibel figure is published by the manufacturer.

What cabling and network gear must I already have to use the 10GbE port on the E10G22-T1-Mini adapter?

The adapter presents one RJ-45 10GbE port. You need Cat6a or better copper cabling and a switch or router with a 10GbE RJ-45 port to utilise the full speed.

Can I keep using my existing 1GbE switches and USB 3.0 backup drives with this unit?

Yes. The RS422+ includes two 1GbE RJ-45 ports with link aggregation and failover, plus one USB 3.2 Gen 1 port for external storage or backup devices.
