Synology RS1626xs+ 4-Bay Rackmount NAS

The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for enterprise workloads. It arrives fully assembled with an Intel Xeon D-1726 processor, 64GB of DDR4 memory, and four 4TB enterprise drives providing 16TB of raw capacity. Dual 10GbE RJ-45 ports and an out-of-band management LAN deliver high-throughput connectivity. A pre-installed 800GB NVMe cache accelerates frequent data access.

Suits virtualisation and multi-user file serving.

This unit suits IT teams running virtual machines, collaborative file shares, or backup targets that benefit from 10GbE speed and NVMe read/write caching. The four-bay chassis limits internal expansion without an additional Synology expansion unit, so buyers who need more than four drives inside a single appliance should look elsewhere. Organisations requiring only 1GbE connectivity or smaller memory footprints can choose a lighter model.

64GB DDR4 ECC memory drives concurrent workloads

The installed 64GB DDR4 ECC RDIMM configuration determines how many virtual machines, containers, or simultaneous users the system can support without paging. Memory is not upgradeable beyond this amount on the RS1626xs+ platform, so capacity planning must start from this fixed 64GB ceiling.

Questions about this item

How much power does the RS1626xs+ draw from a 100-240 VAC supply when running continuously?

The unit operates on 100-240 VAC at 50/60 Hz and is rated for an ambient temperature range of 5°C to 35°C, indicating typical enterprise power draw for a 1U Xeon D-1726 system with four drives and cache installed.

Which cables and drives must I already have to deploy this RS1626xs+ immediately?

The package includes the main unit, accessory pack, two C13-to-C14 power cords, front cover, four pre-installed 4TB Synology Enterprise drives, two 400GB NVMe cache modules, and 64GB DDR4 ECC memory, so only network cables for the two 10GbE RJ-45 ports and the 1GbE management port are required.

Can the RS1626xs+ connect to my existing 1GbE switch while I plan a 10GbE upgrade?

Yes, the two onboard 10GbE RJ-45 ports negotiate down to 1GbE, and the dedicated 1GbE out-of-band management port works on any standard switch, allowing immediate integration with current infrastructure.
