Synology RS1626xs+ 4-Bay 80TB Rackmount NAS

The Synology RS1626xs+ is a 1U rackmount network-attached storage server with four drive bays populated by 20TB enterprise hard drives for 80TB total capacity. An Intel Xeon D-1726 processor and 16GB DDR4 ECC memory power the system. Dual 10GbE RJ-45 ports and a dedicated management LAN connection provide high-throughput networking. The unit arrives fully assembled and tested.

Teams needing dense 10GbE storage.

This appliance suits organisations that want a compact 1U chassis with integrated 10GbE and 80TB of validated enterprise drives for virtualisation, backup or file collaboration. Buyers who require more than four internal bays without adding an expansion unit should consider a larger chassis. Environments that need GPU acceleration or fibre-channel connectivity will not find those interfaces here.

80TB usable capacity from four enterprise drives

The defining specification is the factory-installed 80TB raw capacity delivered by four Synology 20TB enterprise NAS drives. This determines how much data the system can store before any RAID overhead and whether the density meets the project's storage target. All other capabilities scale from this base configuration.

Questions about this item

What rack depth and height does the 1U 4-bay chassis with 44 mm height and 668.5 mm depth require?

The unit occupies one rack unit at 44 mm tall and needs a rack at least 668.5 mm deep; allow extra clearance for the two C13-to-C14 power cords and front cover.

How do I install the Synology 2-Port 10GbE Adapter in the PCIe Gen4 x8 slot, and what step is often missed?

Power down, open the chassis, insert the adapter into the PCIe Gen4 x8 slot until it clicks, secure the bracket, then remember to enable the ports in DSM after reboot.

When should the four 20 TB Synology Enterprise NAS drives be replaced, and what memory upgrade is supported later?

Replace drives when DSM reports degraded health or after the rated workload limit; memory can be expanded from 16 GB to 64 GB using DDR4 ECC RDIMM modules.
