RS3626xs 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server equipped with twelve drive bays. It ships fully assembled and tested with an Intel Xeon D-1726 processor, 48 GB of DDR4 ECC memory, 1.6 TB of enterprise SSD cache, and twelve 24 TB Synology enterprise drives providing 288 TB of raw capacity.

Suits enterprises needing integrated 10GbE

Organisations that require dual 10GbE RJ-45 ports with link aggregation and two PCIe Gen 4 x8 slots for future network or cache upgrades will find this platform ready. Buyers who need more than twelve drive bays or a different form factor should consider alternative platforms.

Twelve 3.5-inch SATA bays define capacity

The chassis accepts exactly twelve 3.5-inch SATA hard drives or 2.5-inch SATA SSDs, fixing the maximum internal drive count at twelve. This bay count, combined with the pre-installed 24 TB drives, sets the total raw storage at 288 TB.

Questions about this item

How do I install the RS3626xs into a rack, and what step is commonly missed?

Secure the 2U chassis using the supplied accessory pack; the step often missed is connecting both C13 to C14 power cords to separate circuits for full redundancy

What maintenance or replacement will the RS3626xs need later?

Replace the twelve 24TB Synology Enterprise drives or the two 800GB cache modules when they reach their rated endurance or if SMART alerts indicate degradation

What limit appears first on the RS3626xs during sustained workloads?

Sequential write throughput caps at 3,700 MB/s under Synology test conditions, becoming the bottleneck before the 10GbE ports or CPU saturate
