Silver 1U rackmount NAS with four drive bays visible

Compact 1U Rackmount NAS

The Synology RS422+ is a 4-bay rackmount network-attached storage server delivered fully assembled with four 12TB enterprise-class drives for 48TB total capacity. It runs the DiskStation Manager operating system and targets small businesses and homelab owners who need centralised file storage, sharing, synchronisation and backup in a space-saving chassis.

Dual 1GbE Network Limits

Two RJ-45 Gigabit ports provide link aggregation and failover, capping throughput at one gigabit per second per port unless aggregation is configured. A single USB 3.2 Gen 1 port allows direct-attached expansion or backup. The AMD Ryzen processor and 2GB of installed memory set the ceiling for concurrent services and virtual machines.

Upgrade From Standalone Drives

This unit replaces loose external drives or a basic file server by consolidating 48TB into a 44mm high rack enclosure with redundant networking. The jump is worth it when you need DSM applications, snapshot-based protection and hot-swappable bays in a 1U form factor. It is not suited for workloads that demand 10GbE speeds, larger memory pools or more than four drive bays.

Questions about this item

Should I choose the 48TB configuration or look for a different capacity?

This unit ships with four 12TB Synology Enterprise Series drives for 48TB raw capacity. The RS422+ has four bays, so capacity is set by the installed drives.

What does the AMD Ryzen processor mean for everyday file serving?

The Ryzen CPU runs Synology DSM to handle file sharing, synchronization and backup tasks for small business or homelab workloads.

How do the two 1GbE ports with link aggregation affect network throughput?

Dual Gigabit RJ-45 ports support link aggregation and failover, allowing combined throughput up to 2Gbps or redundancy if one link fails.
