Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for business workloads that demand high capacity and fast network throughput. It arrives fully assembled and tested with twelve 4TB enterprise-class SATA drives installed, delivering 48TB of raw storage out of the box. A 6-core Intel Xeon D-1726 processor and 32GB of DDR4 ECC memory provide the compute headroom for virtualization, file services and multi-site collaboration.

Suited for high-throughput file and backup workloads

This platform suits IT teams that need integrated 10GbE and 25GbE connectivity plus redundant power supplies to protect service availability. The two PCIe Gen 4 x8 slots allow future addition of compatible network adapters or SSD caching hardware as requirements grow. Buyers who need a compact desktop chassis, single-drive simplicity or a lower drive-count enclosure should evaluate other solutions, as this unit occupies 2U of rack space and populates twelve bays.

12 x 4TB enterprise SATA drives included

The defining specification is the factory-installed set of twelve 4TB Synology enterprise NAS drives, giving 48TB total capacity before RAID configuration. All drives are 3.5-inch SATA models validated for continuous operation in the RS3626xs, so the system is ready for array creation immediately after racking. No additional drive procurement or compatibility checking is required for the initial deployment.
