Ready-to-run 12-bay rackmount NAS

This Synology RS3626xs arrives fully assembled with 192 TB of enterprise storage installed across twelve 16 TB drives. A 6-core Intel Xeon D-1726 processor and 16 GB of DDR4 ECC memory power file services, virtualization and surveillance workloads from day one.

Sustained throughput under heavy workloads

Synology reports sequential reads beyond 6 300 MB/s and writes beyond 3 700 MB/s in its own test conditions. Dual integrated 10 GbE ports and the included 25 GbE SFP28 adapter maintain bandwidth during backups, replication and multi-user access without thermal throttling.

Slide-in drive trays and PCIe expansion

Tool-less 3.5-inch trays let you swap any of the twelve drives while the system runs. Two PCIe Gen 4 x8 slots accept additional network or caching cards, though the 2U depth limits card length. Buyers who need more than 48 GB of memory or a different drive count cannot change those limits on this chassis.

Questions about this item

How much heat does the RS3626xs produce when all twelve 16 TB drives and the 25 GbE adapter run continuously?

The unit is rated to operate between 0 °C and 35 °C ambient with redundant power supplies, so sustained workloads stay within that envelope.

Which cables and transceivers do I need to use the two 25 GbE SFP28 ports on the included adapter?

The SFP28 ports accept standard 25 GbE SFP28 modules and matching fibre or direct-attach cables; the two 10 GbE RJ-45 ports use ordinary Cat 6a or better copper.

Can the twelve 3.5-inch SATA bays accept the 2.5-inch SATA SSDs I already own?

Yes, the chassis supports both 3.5-inch SATA HDDs and 2.5-inch SATA SSDs in the same twelve drive bays.
