Synology RS1626xs+ 4-Bay Rackmount NAS

The Synology RS1626xs+ is a 1U 4-bay rackmount NAS powered by an Intel Xeon D-1726 processor with 64GB DDR4 memory installed. It includes 16TB of raw storage across four 4TB Synology Enterprise drives and a 2-port 25GbE SFP28 adapter. The unit arrives fully assembled and tested.

Suits high-speed 25GbE networks not 10GbE-only

This NAS suits organisations that need 25GbE connectivity for virtualisation, backup or file collaboration workloads. The dual SFP28 ports and Xeon CPU handle concurrent tasks and snapshot-heavy workflows. Buyers limited to 10GbE RJ-45 infrastructure or requiring more than four drive bays without an expansion unit should consider other platforms.

2-port 25GbE SFP28 adapter defines network fit

The included Synology 2-port 25GbE PCIe card provides two SFP28 lanes alongside the built-in dual 10GbE RJ-45 ports and a dedicated management LAN. This combination decides whether the appliance matches your switch fabric and throughput targets.

Questions about this item

What thermal limit applies when the RS1626xs+ runs continuously at full load?

The operating range tops out at 35 °C, so sustained workloads must keep the rack inlet at or below that temperature.

How much power does the Xeon D-1726 system draw during all-day operation?

The dual C13 cords feed a 100-240 VAC 50/60 Hz supply rated for the 64 GB DDR4 configuration and four 4 TB enterprise drives.

Which network infrastructure is needed to use the 25 GbE ports on the installed PCIe card?

SFP28 transceivers and matching switch ports are required; the card provides two 25 GbE links alongside the two built-in 10 GbE RJ-45 ports.
