Synology RS1626xs+ 4-Bay Rackmount NAS

The Synology RS1626xs+ is a 1U rackmount NAS built for enterprise workloads. It ships fully assembled with an Intel Xeon D-1726 processor, 32GB DDR4 ECC memory, 3.2TB NVMe cache and four 16TB enterprise drives installed.

Suits virtualisation and multi-user file services.

This configuration suits teams running virtual machines, container workloads, high-concurrency file sharing or backup targets that benefit from 10GbE connectivity and NVMe read-write cache. Buyers needing GPU acceleration, more than four internal drive bays without an expansion unit, or a tower form factor should consider other platforms.

Four drive bays with dual 10GbE and NVMe cache

The chassis provides four 3.5-inch bays populated with 64TB of raw capacity, two 10GbE RJ-45 ports, a dedicated management LAN port and two M.2 NVMe slots occupied by 1.6TB cache modules, delivering the throughput needed for latency-sensitive applications.

Questions about this item

How do I verify the RS1626xs+ is operating correctly after initial setup?

Log into DiskStation Manager, open Storage Manager and confirm all four 16 TB drives show Healthy with the 64 TB volume mounted. Check that the two 1.6 TB NVMe cache modules appear as read-write cache and that both 10 GbE RJ-45 ports report link speed. The front Power, HDD and LAN LEDs should be solid green.

What ships with the RS1626xs+ and what must I source separately?

The package contains the main unit, accessory pack, two C13-to-C14 power cords, a front cover and all configuration items. The 32 GB DDR4 ECC RDIMM, 3.2 TB NVMe cache and four 16 TB enterprise drives are pre-installed. Additional expansion units, extra RAM up to 64 GB or PCIe cards are purchased separately.

Which RS1626xs+ configuration should I choose for virtualization workloads?

This single SKU already includes the Xeon D-1726 six-core CPU, 32 GB DDR4 ECC memory, 3.2 TB NVMe read-write cache and 64 TB of enterprise drives. It is the maximum factory-assembled specification offered, so no further capacity or cache options exist for this model.
