Synology RS1626xs+ 4-Bay Rackmount NAS
The Synology RS1626xs+ is a 1U rackmount NAS built for enterprises that need high-throughput file services, virtualization hosting and backup consolidation in a compact form factor. It ships fully assembled with an Intel Xeon D-1726 processor, 64GB DDR4 ECC memory, 1.6TB NVMe cache and four 8TB enterprise drives pre-installed. The platform runs Synology DSM and supports expansion to sixteen drives with a compatible expansion unit.
Verify rack depth power and network before ordering
Confirm your cabinet can accommodate a depth of 668.5 mm and provides two C13 outlets for the redundant 100-240 VAC power supplies. The unit requires two 10GbE RJ-45 uplinks plus a dedicated 1GbE management port, so ensure switch ports and cabling are available. Operating temperature must stay between 5 °C and 35 °C with humidity below 80 % RH, and the 9.5 kg weight needs suitable rack rails.
Sustained load performance with Xeon and NVMe cache
Under continuous multi-user workloads the Xeon D-1726 six-core CPU maintains steady throughput for VM hosting and encrypted file transfers without thermal throttling. The 1.6TB NVMe read-write cache absorbs random I/O bursts, keeping latency low during prolonged backup windows or surveillance ingest. Dual 10GbE links and ECC memory prevent data-path bottlenecks and silent corruption during extended operation.

Questions about this item
Does the RS1626xs+ arrive with the 32TB of drives and the 1.6TB cache already installed?
Yes — the unit ships fully assembled and tested with four 8TB enterprise drives and two 800GB NVMe cache modules pre-installed.
Should I choose the 64GB configuration or add more memory later?
The system includes 64GB of DDR4 ECC RDIMM, which is the maximum supported capacity for the Xeon D-1726 processor.
How do the dual 10GbE RJ-45 ports benefit a virtualization host?
They provide 10Gbps network bandwidth for live migration, iSCSI storage traffic, and high-throughput VM workloads without a separate NIC.
