Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need high-capacity, centrally managed data storage. It ships fully assembled with twelve 24 TB enterprise drives installed, delivering 288 TB of raw capacity, and is powered by a 6-core Intel Xeon D-1726 processor with 48 GB of DDR4 ECC memory.

Suited for virtualisation

This system targets IT teams running virtual machines, hosting surveillance archives, or synchronising large datasets across locations. The dual 10GbE RJ-45 ports and two PCIe Gen 4 x8 slots support bandwidth-heavy workloads. Buyers who need all-flash performance or a smaller desktop form factor should evaluate other platforms.

288 TB of pre-installed enterprise drives

The defining specification is the twelve 24 TB Synology Enterprise NAS drives that come installed and tested. This capacity determines how much primary data, backup retention, or surveillance footage the appliance can hold before expansion units are added.

Questions about this item

How often will the twelve 24 TB SATA drives need to be replaced in a RAID array?

Drive lifespan depends on workload and environment; Synology Enterprise drives are rated for continuous operation, and the RS3626xs supports hot-swap replacement without downtime.

What throughput limit appears first during sustained 10 GbE transfers?

Sequential reads can exceed 6,300 MB/s and writes 3,700 MB/s under Synology test conditions, so the 10 GbE link is typically the bottleneck before the drives saturate.

How much heat and noise does the 2U chassis produce when running all day?

Dual redundant power supplies and multiple fans keep the system within the 0–35 °C operating range; acoustic output scales with drive count and fan speed under load.
