Synology RS3626xs 12-Bay Rackmount NAS Xeon D-1726 16GB 48TB

Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need centralized file storage, data protection, virtualization, and surveillance capacity. It ships fully assembled with twelve 4 TB enterprise-class SATA drives pre-installed, delivering 48 TB of raw capacity out of the box. A 6-core Intel Xeon D-1726 processor and 16 GB of DDR4 ECC memory provide the compute headroom for demanding multi-user workloads.

Dual 10GbE and PCIe Gen 4 expansion

Two integrated 10GbE RJ-45 ports support link aggregation for higher throughput, load balancing, and network failover without extra cards. Two PCIe Gen 4 x8 slots remain open for adding compatible 10GbE or 25GbE adapters, Fibre Channel connectivity, or SSD caching hardware as requirements grow. Redundant power supplies and an out-of-band management port help maintain service availability and simplify remote administration.

Sustained sequential throughput

Synology reports sequential read performance exceeding 6,300 MB/s and write performance exceeding 3,700 MB/s under its test conditions, indicating strong sustained transfer rates for large-file workloads such as backup, media editing, and virtualization storage. The system operates within a 0 °C to 35 °C temperature range and 8 % to 80 % relative humidity, and the Xeon D-1726 platform is designed for continuous operation in rack environments.
