12-Bay Rackmount NAS with Xeon D-1726

The Synology RS3626xs is a 2U, 12-bay enterprise NAS powered by a 6-core Intel Xeon D-1726 processor. It ships fully assembled with 32GB DDR4 ECC memory, 800GB of enterprise cache, and twelve 16TB Synology drives providing 192TB total capacity. Designed for centralised file storage, virtualisation, and multi-site collaboration.

Suits teams needing integrated 10GbE

Two built-in 10GbE RJ-45 ports support link aggregation and failover for high-throughput workloads. Two PCIe Gen 4 x8 slots allow adding 25GbE, Fibre Channel, or additional caching cards. Organisations requiring higher compute density or GPU acceleration should evaluate alternative platforms.

192TB raw capacity with 800GB cache tier

The array delivers 192TB raw storage across twelve 3.5-inch SATA bays populated with Synology Enterprise drives. A dedicated 800GB cache layer accelerates frequent read and write operations. Buyers needing larger single volumes or different drive formats must plan expansion separately.
