Synology RS3626xs Xeon D-1726 12-bay rackmount NAS 16GB 3.2TB cache 192TB

Purpose-built 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server equipped with twelve drive bays, a 6-core Intel Xeon D-1726 processor, 16 GB of DDR4 ECC memory, 3.2 TB of enterprise SSD cache, and 192 TB of pre-installed Synology enterprise hard drives. It targets organisations that need a fully assembled, high-capacity platform for centralised file storage, virtualization, backup, and surveillance workloads. Buyers who require more than twelve bays or a different processor class should consider alternative chassis configurations.

Thermals, noise and power draw

The unit operates from a 100-240 VAC 50/60 Hz supply with redundant power supplies fitted as standard. Synology specifies an operating temperature range of 0 °C to 35 °C and a humidity range of 8 % to 80 % RH. The 2U form factor measures 88 mm high, 482 mm wide and 724 mm deep, weighing 14.5 kg when fully populated. No acoustic or typical power-consumption figures are published by the manufacturer.

Sustained-load behaviour

Under Synology test conditions the system achieves sequential read throughput above 6,300 MB/s and sequential write throughput above 3,700 MB/s using the integrated 10 GbE RJ-45 ports with link aggregation. Two PCIe Gen 4 x8 slots remain available for additional network adapters, Fibre Channel cards or further cache devices if workloads demand expanded I/O bandwidth. The platform supports memory expansion up to 48 GB and can scale raw capacity beyond the factory 192 TB through compatible expansion units.
