4-Bay Rackmount NAS with Xeon D-1726
The Synology RS1626xs+ is a 1U rackmount network-attached storage system built for businesses that require high-performance file sharing, virtualization, and backup in a compact form factor. It ships fully assembled with 64GB of DDR4 ECC memory and 64TB of raw capacity across four 16TB enterprise drives. Dual 10GbE RJ-45 ports and a dual-port 25GbE SFP28 adapter provide flexible high-speed connectivity.
Sustained throughput with 25GbE and ECC memory
Under continuous load the Xeon D-1726 six-core processor maintains consistent compute performance for multi-user access and virtual machine workloads. The installed 64GB DDR4 ECC RDIMM memory protects data integrity during extended operations, while the 25GbE SFP28 ports sustain high bandwidth for backup replication and intensive file transfers without thermal throttling in the 1U chassis.
64TB pre-populated with Synology Enterprise drives
The decisive specification is the factory-installed 64TB array using four 16TB Synology Enterprise NAS drives, delivering immediate capacity for mission-critical datasets. Buyers who need a different drive count, larger single volumes, or a separate expansion unit for scaling beyond four bays should evaluate alternative configurations.

Questions about this item
How loud or hot does the RS1626xs+ get when it runs 24/7 with four 16TB drives?
The unit operates between 5°C and 35°C with humidity from 8% to 80% RH, drawing 100–240 VAC at 50/60 Hz in a 1U chassis that weighs 9.5 kg.
Which cables and network gear do I need to use the 25GbE SFP28 ports on the included PCIe card?
You need SFP28 transceivers or direct-attach cables compatible with 25GbE and a switch that supports 25GbE on SFP28 interfaces.
Can I keep my existing 10GbE RJ-45 switches and still connect this NAS at full speed?
Yes, the RS1626xs+ has two built-in 10GbE RJ-45 LAN ports that work directly with your current 10GbE copper infrastructure.
