Synology RS3626xs 12-Bay Rackmount NAS Xeon D-1726 32GB 3.2TB Cache 96TB Drives

12-Bay Enterprise Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity, centralised file storage and data protection. It arrives fully assembled with twelve 8TB enterprise drives, 32GB of DDR4 ECC memory, and 3.2TB of SSD cache. The Xeon D-1726 processor handles virtualisation, surveillance, and multi-site collaboration workloads.

Dual 10GbE and PCIe Gen 4 Expansion

Network connectivity relies on two integrated 10GbE RJ-45 ports that support link aggregation for higher throughput and failover. Sequential read performance exceeds 6,300 MB/s and write reaches 3,700 MB/s under vendor test conditions. Two PCIe Gen 4 x8 slots allow the addition of 25GbE adapters, Fibre Channel cards, or extra cache hardware as requirements grow.

Twelve 3.5-Inch Drive Bays Limit Raw Capacity

The chassis accepts exactly twelve 3.5-inch SATA hard drives or 2.5-inch SATA SSDs, fixing the maximum number of installed drives at twelve. Buyers who need more raw storage bays must look at larger chassis or expansion units. Memory can be increased to 48GB, but the drive bay count is a hard physical constraint.
