Synology RackStation RS1221+ 8 Bay 4GB RAM Diskless 2RU Rack Mountable NAS

A powerful storage solution for businesses and IT enthusiasts with redundancy and service continuity features.

A compact design for space efficiency:
The RS1221+ is designed to help you save space in compact deployments. At only 30 centimetres, half the length of a typical 2U unit, it fits perfectly snug onto 2-post or shallow rackmount enclosures.

Redundant power:
Reduce the chance that power disruptions on a single distribution channel or PDU causes data and service availability degradation.

Maximise service availability:
When paired with another identical unit, Synology High Availability enables automatic minute-level failover between two clustered servers in the event of a server failure to minimise service downtime.

Data integrity and protection:
ECC memory and the Btrfs file system bring higher reliability and snapshot capabilities to help prevent data corruption and simplify data protection.

High performance storage for anything:
Up to 2,315/1,147 MB/s sequential read and write throughput and over 100K/54K random read/write IOPS ensures ample performance for demanding workloads.
