A compact design for space efficiency

The RS1221+ and its RX418 expansion units are designed to help you save space in compact deployments. At only 30 centimeters, half the length of a typical 2U unit, it fits perfectly snug onto 2-post or shallow rackmount enclosures. The RS1221RP+ with dual power supplies comes in at 38 cm, also fitting most shallow depth enclosures.

  • Fits into shallow rackmount enclosures
  • Easy-to-install on 2-post racks

Built for reliability

Redundant power

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

Maximize 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 minimize service downtime.Learn more

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.Learn more

Built for reliability

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.

The RS1221+ features 285% faster random 4K IOPS reads and 117% faster random 4K IOPS writes compared to its predecessor
The RS1221+ features 62% faster sequential reads and 137% faster sequential writes compared to its predecessor
With room to grow with you Easily upgrade the RS1221RP+/RS1221+ 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-in
Maximize 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. Learn more
Protect your entire IT infrastructure Protect your entire office with Active Backup The Active Backup suite enables administrators to easily secure their entire IT infrastructure by backing up mission-critical data to their NAS, including Windows & Linux workstations and servers, file servers, VMware and Hyper-V virtual machines, and Microsoft 365 and Google Workspace accounts. Benefit from deduplication, multiversioning to quickly jump back in time, and additional data efficiency optimizations for reduced bandwidth and storage use. Learn more

Hardware Overview

Notes: Performance testing conducted by Synology with 10GbE NIC installed. Actual results may vary depending on system configuration, testing methods, and other environmental variables. Check the performance page for additional details. Compared to typical 2U rackmount chassis depth of 24" (61cm) or more. Actual fit will may depend on cabinet design, including usable space, cable routing, weight tolerance, and more. Synology is unable to provide guidance on compatibility with specific rackmount equipment. Network adapter cards, expansion units, other PCIe add-in-cards, and storage drives are sold separately. Refer to the compatibility list for compatible devices. Learn more NVMe SSD cache can be enabled via a M2D20 or E10M20-T1 PCIe expansion card and 2x Synology SNV3400/3500 M.2 NVMe SSDs. Read/write SATA SSD cache can be enabled via 2x Synology SAT5200 2.5" SATA SSDs.
