Synology RS1626xs+ Intel Xeon D-1726 4-Bay Rackmount NAS 16GB RAM 800GB Cache 64TB Drives

4-bay Xeon rackmount NAS

The Synology RS1626xs+ is a 1U enterprise network-attached storage server built around an Intel Xeon D-1726 processor with 16GB of DDR4 ECC memory. It ships fully assembled with four 16TB Synology enterprise drives providing 64TB of raw capacity and two 400GB NVMe cache modules totalling 800GB. Dual 10GbE RJ-45 ports and a dedicated management LAN give it the connectivity profile expected in a server-room deployment.

Upgrade from single-GbE or smaller bays

The jump is worth it when a team outgrows a 1GbE NAS that bottlenecks virtual-machine storage or multi-user file sharing, or when a two-to-four-bay unit can no longer hold the working set. Ten-gigabit networking and hardware-accelerated encryption remove the throughput ceiling that stalls backup windows and database workloads. The PCIe Gen4 x8 slot and expansion-unit support let capacity grow without a forklift migration.

Sustained load behaviour

Under continuous virtualization or backup streams the Xeon D-1726 maintains steady multi-core throughput while ECC memory corrects single-bit errors before they corrupt datasets. The NVMe cache absorbs write bursts so the enterprise hard drives see sequential patterns, preserving both latency consistency and drive longevity. Operating between 5°C and 35°C with dual power cords, the chassis is rated for 24/7 duty in standard rack environments.
