12-Bay Rackmount NAS for Enterprise Workloads

The Synology RS3626xs is a 2U rackmount network-attached storage system fitted with twelve drive bays. It ships fully assembled with a 6-core Intel Xeon D-1726 processor, 32 GB of DDR4 ECC memory and fourteen terabytes of raw capacity spread across twelve Synology Enterprise SATA drives. Dual redundant power supplies and an out-of-band management port are included.

Suited for Centralised File Storage

This platform targets organisations that need high-capacity shared storage, backup targets or virtualisation hosts with integrated 10 GbE and 25 GbE connectivity. Buyers who require a smaller form factor, fewer drive bays or a lower acquisition cost should evaluate alternative models.

Twelve 12 TB Enterprise SATA Drives Pre-Installed

The decisive specification is the factory-fitted drive set: twelve 12 TB Synology Enterprise SATA drives delivering 144 TB raw capacity. Confirm that your workload fits within this capacity and that SATA performance meets your throughput requirements before purchase.
