Synology RS1221RP+ 8-Bay RackStation NAS Diskless

The Synology RS1221RP+ is an 8-bay rackmount NAS built for small and medium-sized businesses that require reliable, high-performance networked storage. With sequential read speeds reaching up to 2,315 MB/s and write speeds up to 1,147 MB/s, it handles multi-user file access, virtualization storage, and backup workloads without bottlenecking. The unit ships with 4GB of DDR4 RAM and includes a PCIe Gen3 expansion slot, allowing administrators to install a 10GbE SFP+ or RJ-45 network interface card or an M.2 SSD adapter to boost network throughput or add NVMe caching, respectively.

The "RP+" designation reflects the inclusion of redundant power supplies — a critical feature for environments where downtime carries real cost. If one power supply fails, the second maintains operation without interruption while the failed unit is replaced. For organizations requiring even greater uptime guarantees, two RS1221RP+ units can be configured as a Synology High Availability cluster, providing automatic failover with minute-level recovery time. The 2U rackmount form factor with a 399mm depth fits standard server racks, and dual Gigabit Ethernet ports support link aggregation or failover at the network level. Sold diskless, it gives administrators the flexibility to choose drives that match their capacity, performance, and redundancy requirements.
