Synology RS3626xs 12-bay rackmount NAS

The Synology RS3626xs is a 12-bay rackmount NAS powered by an Intel Xeon D-1726 processor with 8GB of DDR4 ECC memory. It arrives fully assembled and tested with twelve 8TB Synology Enterprise SATA drives providing 96TB of raw capacity. This system targets businesses that need centralised file storage, virtualisation support, and multi-site collaboration in a 2U form factor.

Build quality and daily connectivity

Dual redundant power supplies protect uptime against a single power-supply failure. The front panel holds twelve hot-swap drive bays for 3.5-inch SATA HDDs or 2.5-inch SATA SSDs behind a lockable cover. Rear I/O includes two 10GbE RJ-45 ports with Link Aggregation support, a dedicated out-of-band management LAN port, and two USB 3.2 Gen 1 ports for backup targets or peripheral expansion. Two PCIe Gen 4 x8 slots allow future addition of compatible network adapters or SSD caching hardware.

96TB of pre-installed enterprise storage

The unit ships with 96TB (12 x 8TB) of Synology Enterprise NAS drives already installed and configured. Memory is expandable to 48GB to support heavier virtualisation or database workloads. Sequential throughput reaches 6,300 MB/s read and 3,700 MB/s write under Synology test conditions. Buyers who need more than twelve drive bays or a different drive type must look at other platforms.

Questions about this item

What bandwidth do the two integrated 10GbE RJ-45 ports deliver in practice?

Synology reports sequential performance exceeding 6,300 MB/s read and 3,700 MB/s write under its test conditions; Link Aggregation can combine the two ports for higher throughput and failover.

What physical space and drive sizes does the 12-bay chassis accept?

The 2U rackmount unit measures 88 mm × 482 mm × 724 mm and weighs 14.5 kg; it holds twelve 3.5-inch SATA HDDs or 2.5-inch SATA SSDs in the front bays.

How is the included memory installed and what mistake should be avoided?

The system ships with 8 GB of DDR4 ECC memory already installed in the main unit; the common error is forgetting that expansion requires Synology DDR4 ECC modules to reach the 48 GB maximum.
