4-Bay Rackmount NAS for Enterprise Workloads
The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for businesses that require high-performance file sharing, virtualization, and backup. It ships fully assembled with an Intel Xeon D-1726 processor, 32GB of DDR4 ECC memory, and four enterprise-class drives pre-installed for immediate deployment.
16TB Raw Storage with 1.6TB NVMe Cache
The unit provides 16TB of raw capacity across four 4TB Synology Enterprise drives, complemented by two 800GB NVMe SSDs configured as read-write cache. This combination handles mixed random I/O and metadata-heavy applications comfortably, while the four-bay chassis limits total internal drive expansion without an external expansion unit.
Dual 10GbE and PCIe Expansion in 1U
Dual RJ-45 10GbE LAN ports and a dedicated out-of-band management port deliver high-throughput connectivity straight from the chassis. A PCIe Gen4 x8 slot allows adding a network adapter or HBA, and the included C13-to-C14 cords support redundant power distribution. The short 668.5mm depth fits shallow racks, though the fixed rail kit requires compatible square-hole mounting.

Questions about this item
Will the dual 10GbE RJ-45 ports work with my existing 1GbE switch?
Yes, the 10GbE ports auto-negotiate down to 1GbE so the NAS connects to your current switch at its maximum speed.
How can I confirm the 1.6TB NVMe cache is active after setup?
In DSM open Storage Manager → SSD Cache to see both 800GB modules recognised and the cache status showing "Normal".
Are the four 4TB enterprise drives and both 800GB cache modules already installed?
The unit ships fully assembled with the 16TB of drives and the 1.6TB cache pre-installed; only network cables and a rack rail kit need to be added.
