Purpose-built 4-bay rackmount NAS

The Synology RS1626xs+ is a 1U enterprise network-attached storage server powered by an Intel Xeon D-1726 processor with 32GB of installed DDR4 memory. It arrives fully assembled and tested with four 4TB Synology Enterprise drives providing 16TB of raw capacity, ready for immediate deployment in business environments.

Suits virtualization and multi-user file sharing

Organizations running virtual machines, container workloads or high-concurrency file access will benefit from the six-core Xeon CPU and dual 10GbE RJ-45 ports. Buyers needing more than four drive bays without adding an expansion unit, or those requiring fibre-channel connectivity, should evaluate alternative platforms.

Dual 10GbE networking decides fit

Two built-in 10GbE RJ-45 LAN ports provide high-throughput connectivity for demanding workloads without additional cards. If the network infrastructure operates at 1GbE only, the extra bandwidth remains unused and a lower-tier model may suffice.

Questions about this item

How do I install the RS1626xs+ into a rack and what step is commonly missed?

Secure the 1U chassis in a standard rack using the included accessory pack, connect both C13 to C14 power cords, attach the 10GbE and management LAN cables, then configure DSM via the web interface before creating storage volumes.

What maintenance or replacement will the RS1626xs+ need over time?

The four 4TB Synology Enterprise drives may require replacement after their rated workload limit; the 32GB DDR4 ECC RDIMM can be expanded to 64GB; M.2 NVMe cache modules and the PCIe Gen4 x8 card can be added or swapped later.

What limit appears first under sustained heavy workloads on the RS1626xs+?

The Xeon D-1726 6-core processor and 32GB DDR4 memory set the compute ceiling; dual 10GbE ports cap network throughput; operating temperature must stay within 5°C to 35°C to avoid thermal throttling.
