Ready-to-run 4-bay rack NAS
The Synology RS1626xs+ arrives fully assembled with an Intel Xeon D-1726 processor, 16GB DDR4 ECC memory, 1.6TB NVMe cache and four 16TB enterprise drives delivering 64TB raw capacity. Dual 10GbE RJ-45 ports and a dedicated management LAN provide high-speed connectivity out of the box. DSM software adds snapshot replication, virtualization support and hybrid cloud integration for business workloads.
Suits teams needing immediate capacity
Organisations that want a validated, pre-configured appliance for file sharing, backup or surveillance without drive installation effort will benefit. Buyers who require more than four drive bays, larger memory than 16GB, or different drive capacities should look at other configurations. The 1U form factor fits standard racks but lacks redundant power supplies.
64TB pre-populated enterprise storage
Four Synology 16TB drives ship installed and tested, providing 64TB of raw capacity before RAID overhead. The 1.6TB cache uses two 800GB NVMe modules to accelerate random I/O for databases and virtual machines. This combination determines whether the appliance meets performance and capacity targets for the intended workload.

Questions about this item
What rack depth does the 44 mm high RS1626xs+ require?
The unit is 668.5 mm deep and fits a standard 1U rack space; allow extra depth for the two C13-to-C14 power cords and cable routing at the rear.
How are the two 800 GB NVMe cache modules installed, and what step is often missed?
Insert each module into an internal M.2 slot at the correct angle, press down, and secure with the screw; the step often missed is removing the protective film from the thermal pad before closing the chassis.
Which drives will need replacement first in this fully assembled unit?
The four 16 TB enterprise HDDs and the two 800 GB NVMe cache modules are the only field-replaceable storage components; both types are hot-swappable via the front drive bays and internal M.2 slots respectively.
