4-Bay Rackmount NAS with Xeon D-1726
The Synology RS1626xs+ is a 1U enterprise NAS built for businesses that need reliable file sharing, backup and virtualization in a compact rackmount form. It ships fully assembled with an Intel Xeon D-1726 processor, 64GB of DDR4 memory and four 12TB Synology Enterprise drives for a total of 48TB raw capacity.
Sustained workload behaviour with ECC memory
The Xeon D-1726 six-core CPU and 64GB DDR4 ECC RDIMM combination maintains consistent throughput during prolonged virtualization, backup and surveillance tasks. ECC memory protects data integrity under continuous load while the 100-240 VAC power supply supports uninterrupted operation within the specified 5°C to 35°C temperature range.
Practical limits of 10GbE and PCIe Gen4 expansion
Dual onboard 10GbE RJ-45 ports and a PCIe Gen4 x8 slot provide high-speed networking and cache acceleration via M.2 NVMe SSDs. The 10GbE interface caps real-world throughput at the protocol limit, and the single expansion slot restricts additional controller or NIC upgrades to one device. The four-bay chassis limits internal drive count to four without an external Synology expansion unit.

Questions about this item
How loud and hot does the RS1626xs+ get when it runs 24/7 with the Xeon D-1726 and four 12 TB drives?
The chassis operates between 5 °C and 35 °C ambient and draws 100–240 VAC at 50/60 Hz; fan speed is managed by DSM to balance noise and cooling under load.
Which rails, cables and network infrastructure do I need before the RS1626xs+ can go live?
Two C13-to-C14 power cords are included; you supply the 1U rack rails, Cat 6a or better cabling for the dual 10GbE RJ-45 ports and a management switch for the out-of-band LAN.
Will my existing 1 GbE switches and older USB 2.0 backup drives work with this unit?
The 10GbE ports auto-negotiate down to 1 GbE, and the two USB 3.2 Gen 1 ports are backward compatible with USB 2.0 devices for backup or licensing keys.
