Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage system powered by a 6-core Intel Xeon D-1726 processor and 16GB of DDR4 ECC memory. It arrives fully assembled and tested with twelve 4TB Synology Enterprise SATA drives providing 48TB of raw capacity. Two integrated 10GbE RJ-45 ports and two USB 3.2 Gen 1 ports handle high-speed connectivity.

Suited for centralised file storage

This unit suits organisations that need redundant power supplies, out-of-band management and the ability to expand via two PCIe Gen 4 x8 slots for additional network adapters or SSD caching hardware. Buyers who require more than twelve drive bays, higher installed memory than 16GB, or a tower form factor should look at something else because this configuration is fixed at 12 bays and a rackmount chassis.

48TB of pre-installed Enterprise SATA storage

The decisive specification is the included set of twelve 4TB Synology Enterprise drives delivering 48TB total capacity in a RAID-ready configuration. Each drive uses a 3.5-inch SATA interface and the chassis supports both 3.5-inch HDDs and 2.5-inch SSDs for future expansion. This capacity and drive type determine whether the system matches your storage workload and redundancy plan.

Questions about this item

Will the Xeon D-1726 throttle under continuous multi-user file serving and virtualization loads?

The 6-core Xeon D-1726 with 16 GB DDR4 ECC memory is designed for sustained enterprise workloads; Synology specifies an operating range of 0 °C to 35 °C to maintain performance without thermal throttling.

How loud and hot does the RS3626xs get when all twelve 4 TB drives and both 10 GbE ports run 24/7?

Dual redundant power supplies and multiple system fans keep the 2U chassis within the rated 0 °C to 35 °C range; acoustic output is typical for a rackmount server in a data-centre aisle.

What network infrastructure must already be in place to use the two onboard 10 GbE RJ-45 ports at full speed?

A 10 GBASE-T switch or router with Cat 6a or better cabling is required; the ports also negotiate down to 1 GbE or 100 MbE if the existing network only supports those speeds.
