12-Bay Enterprise Rackmount NAS

The Synology RS3626xs is a 2U rackmount NAS built for organisations that need high-capacity, centralised file storage and data protection. It ships fully assembled with twelve 24 TB enterprise drives, 16 GB of DDR4 ECC memory, and 3.2 TB of SSD cache for accelerated workloads.

Dual 10GbE Ports and PCIe Expansion

Two integrated 10GbE RJ-45 ports support link aggregation and failover, while two PCIe Gen 4 x8 slots allow further network or cache upgrades. Redundant power supplies and a dedicated out-of-band management port keep the system manageable during a power-supply failure.

Scalable to 48 GB Memory

The Xeon D-1726 processor handles virtualization, surveillance, and multi-site collaboration, with memory expandable to 48 GB. Buyers who require greater raw capacity or higher memory ceilings will need a larger chassis or a different platform.
