Synology RS3626xs 12-Bay Rackmount NAS Xeon D-1726 48GB 3.2TB Cache 48TB Drives

12-bay rackmount NAS with Xeon D-1726

The Synology RS3626xs is a 2U rackmount network-attached storage server built around a 6-core Intel Xeon D-1726 processor. It ships with 48 GB of DDR4 ECC memory and twelve drive bays populated by 4 TB Synology Enterprise NAS drives. The platform targets businesses that need centralised file storage, virtualization hosting, or multi-site collaboration in a single appliance.

3.2 TB Enterprise cache and dual 10GbE ports

Two 1.6 TB Synology Enterprise cache modules accelerate frequent read and write operations across the volume. Dual integrated 10GbE RJ-45 ports support link aggregation for higher throughput and automatic failover. Two PCIe Gen 4 x8 slots remain available for additional network adapters, Fibre Channel cards, or extra caching hardware as requirements change.

48 TB raw capacity with room to expand

The twelve installed 4 TB drives provide 48 TB of raw capacity for large datasets, backup targets, or surveillance archives. Sequential performance reaches 6,300 MB/s read and 3,700 MB/s write under Synology test conditions. Organisations needing more than twelve bays or denser flash storage will need a different chassis or expansion units.
