Synology RS3626xs Xeon D-1726 12-Bay rackmount NAS 48GB 3.2TB cache 192TB

12-Bay Rackmount NAS with Xeon D-1726

The Synology RS3626xs is a 2U enterprise network-attached storage server built around a 6-core Intel Xeon D-1726 processor. It arrives fully assembled with 48GB of DDR4 ECC memory, 3.2TB of enterprise cache via two 1.6TB modules, and twelve 16TB Synology drives providing 192TB of raw capacity. This configuration targets organisations that need immediate, high-density file storage and virtualization support without manual drive installation.

Verify 10GbE switch ports

The unit provides two integrated 10GbE RJ-45 LAN ports plus a dedicated out-of-band management port, so your network infrastructure must support 10GbE to utilise the native throughput. Two PCIe Gen 4 x8 slots are available for additional network adapters or cache hardware if expansion is planned. Ensure the rack enclosure accommodates the 724mm depth and that the 100-240 VAC power input matches your PDU configuration. The operating temperature range is 0°C to 35°C.

Sustained sequential throughput above 3,700 MB/s

Synology reports sequential read performance exceeding 6,300 MB/s and write performance exceeding 3,700 MB/s under its test conditions, indicating the system maintains high throughput during extended operations rather than only in short bursts. Redundant power supplies protect against single-supply failure during continuous workloads. The Xeon D-1726 and 48GB memory combination supports consistent performance for virtualization, surveillance, and multi-site collaboration tasks over long periods.
