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.

With room to grow with you

Easily upgrade the RS1221+/RS1221RP+ to match your usage environment, whether it's for performance, faster networking, or higher storage capacity.

• SSD cache

  Boost read/write IOPS over HDD-only arrays by 16X or more with NVMe or SATA SSD Cache

• 10GbE ready

  Improve I/O with faster SFP+ or RJ-45 networking

• Storage expansion

  Expand to 12 drive bays with a RX418 expansion unit

Data protection solutions, built-inMaximize data availability

Hyper Backup

A comprehensive backup and recovery solution for added data protection. Create backup destinations locally, on another Synology device, rsync servers, or cloud-based destinations, such as Google Drive, Dropbox, S3-compatible destinations, and Synology C2 Storage, a dedicated backup destination for Synology devices. Deduplication, integrity checks, and incremental transfer technology reduce bandwidth and storage use.Learn more

Snapshot Replication

Easily schedule flexible point-in-time backups of shared folders and LUNs with an RPO as low as 5 minutes and recovery in seconds. Set up replication and failover to other Synology storage systems for fast RTOs and minimal service disruption.
