Synology RS3626xs Xeon D-1726 12-bay rackmount NAS 16GB 800GB cache 192TB

12-bay rackmount NAS for enterprise workloads

The Synology RS3626xs is a 2U rackmount network-attached storage system built around a 6-core Intel Xeon D-1726 processor. It arrives fully assembled with 16GB of DDR4 ECC memory, 800GB of enterprise SSD cache, and twelve 16TB SATA drives providing 192TB of raw capacity. This configuration targets businesses that need immediate, high-capacity storage for virtualization, surveillance, or multi-site file collaboration.

Upgrades from smaller bays or slower interconnects

The twelve drive bays replace 4-bay or 8-bay units when dataset growth exceeds their physical limits. Dual integrated 10GbE RJ-45 ports replace single 1GbE links, enabling link aggregation and failover for heavier concurrent access. Two PCIe Gen 4 x8 slots allow future addition of 25GbE, Fibre Channel, or extra cache cards. The jump is worth it when current throughput or bay count bottlenecks daily operations.

Check rack space, power, and drive compatibility

Verify your rack can accommodate a 2U chassis measuring 88mm high, 482mm wide, and 724mm deep with a 14.5kg installed weight. Confirm 100-240VAC 50/60Hz supply and dual C13/C14 power cords for redundant PSU operation. Ensure the operating environment stays within 0°C to 35°C and 8% to 80% relative humidity. The twelve bays accept 3.5-inch SATA HDDs or 2.5-inch SATA SSDs; no other drive form factors are supported.
