Synology RS3626xs 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for business workloads. It arrives fully assembled and tested with twelve enterprise-class 4TB drives providing 48TB of raw capacity. A 6-core Intel Xeon D-1726 processor and 8GB of DDR4 ECC memory power the platform.

Suits teams needing high-capacity SATA storage

This unit fits organisations that want a ready-to-run rackmount appliance for file services, backup, virtualization or surveillance using 3.5-inch SATA HDDs or 2.5-inch SATA SSDs. Buyers who require all-flash performance, GPU acceleration or densities beyond twelve drive bays should evaluate alternative platforms.

Twelve 3.5-inch SATA bays define the storage limit

The chassis accepts exactly twelve 3.5-inch SATA hard drives or 2.5-inch SATA solid-state drives and cannot be expanded internally beyond that count. Expansion units are supported for additional capacity, but the onboard bay total is fixed at twelve.
