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 16GB DDR4 memory. It arrives fully assembled with four 16TB Synology Enterprise drives for 64TB of raw capacity. Dual 10GbE RJ-45 ports and a dedicated management LAN port provide high-speed network connectivity. Designed for business environments requiring centralized storage and virtualization support.

Teams needing 4-bay 10GbE NAS.

This unit suits teams that need a compact 4-bay server with dual 10GbE links for file sharing, backup or virtualization workloads. Buyers who need more than four internal bays should consider a chassis with additional slots or an expansion unit. Organisations without 10GbE infrastructure will not use the full network potential. Environments outside the 5°C to 35°C operating range require different hardware.

64TB raw capacity with four 16TB enterprise drives

The system includes four 16TB Synology Enterprise NAS drives pre-installed, delivering 64TB of raw storage in a single 1U enclosure. This capacity level determines how much data can be stored before adding an expansion unit. The drives are enterprise-class units validated for continuous operation in the RS1626xs+ platform.

Questions about this item

How can I verify the RS1626xs+ is operating correctly after rack installation?

Check the front Power, HDD and LAN LEDs for normal activity, then log into the DSM web interface to confirm all four 16 TB drives appear healthy and the dual 10 GbE ports show link status.

What ships with the unit and what must I purchase separately?

The package includes the main unit, accessory pack, two C13-to-C14 power cords, a front cover and four pre-installed 16 TB Synology Enterprise drives; additional DDR4 ECC RDIMM modules or M.2 NVMe cache drives are optional upgrades.

Which memory configuration should I select for virtualization workloads?

The system arrives with 16 GB DDR4 ECC RDIMM installed and supports expansion to 64 GB; choose the maximum capacity if you plan to run multiple virtual machines or heavy container workloads.
