4-bay Xeon rackmount NAS for enterprise workloads

The Synology RS1626xs+ is a 1U rackmount NAS built around an Intel Xeon D-1726 6-core processor with 16GB DDR4 ECC memory. It ships fully assembled with four 24TB enterprise drives providing 96TB raw capacity plus 3.2TB NVMe cache. This configuration targets businesses that need virtualization, backup, surveillance and high-performance file sharing in a compact form factor.

Dual 10GbE and PCIe Gen4 x8 expansion limits

Network connectivity relies on two built-in 10GbE RJ-45 ports and a dedicated 1GbE management link. The single PCIe Gen4 x8 slot and dual M.2 NVMe slots are the only internal expansion paths; adding more drives requires a compatible Synology expansion unit. USB 3.2 Gen 1 ports serve peripheral or backup tasks but do not increase internal throughput.

Replaces slower 1GbE or smaller-capacity NAS

Organizations moving from 1GbE-only NAS or from systems without NVMe cache gain the most when workloads saturate gigabit links or demand low-latency metadata operations. The jump is less valuable for cold-archive workloads that never exceed 1GbE throughput or for sites that cannot use the PCIe slot for additional networking or GPU acceleration.
