Compact 1U rackmount NAS with 48 TB storage

The Synology RS422+ is a 4-bay rackmount NAS delivered fully assembled with four 12 TB enterprise drives for 48 TB raw capacity. It runs on an AMD Ryzen processor with 2 GB of installed memory and includes a 10 GbE adapter plus dual 1 GbE ports. The 1U chassis fits standard racks and wall mounts for space-constrained deployments.

Small teams needing ready-to-run file storage

This unit suits small businesses and homelab owners who want an all-in-one solution for data management, sharing, synchronisation and backup without building a server. It is not for buyers who need more than four drive bays, higher base memory or additional PCIe expansion beyond the included 10 GbE adapter.

AMD Ryzen processor drives DSM performance

The AMD Ryzen CPU powers Synology DiskStation Manager for daily workloads including file serving, backup and synchronisation tasks. The 2 GB of installed memory supports these core services while the E10G22-T1-Mini adapter provides 10 GbE connectivity for faster network throughput.

Questions about this item

How do I install the E10G22-T1-Mini 10GbE adapter in the RS422+ and what step is often missed?

Insert the E10G22-T1-Mini into the PCIe slot inside the chassis, secure the bracket screw, then enable the 10GbE port in DSM Control Panel — the step most people miss is enabling the interface in software after the physical install.

Which components in this RS422+ will need replacement first during long-term operation?

The four 12TB Synology Enterprise Series drives are the primary wear items; plan to replace them after their rated workload limit or if SMART alerts appear, while the 2GB soldered RAM and Ryzen processor are not user-replaceable.

What thermal limit appears first when the RS422+ runs sustained workloads in a rack?

The operating temperature ceiling is 35 °C; sustained heavy I/O in a 1U rack can push internal temps toward that limit before network or CPU throttling becomes the bottleneck.
