Synology RS1626xs+ Xeon D-1726 4-Bay Rackmount NAS 64GB 800GB Cache 96TB

4-Bay Rackmount NAS with Xeon D-1726

The Synology RS1626xs+ is a 1U rackmount network-attached storage system built around an Intel Xeon D-1726 processor and 64GB of DDR4 memory. It arrives fully assembled with four 24TB enterprise drives for 96TB of raw capacity and two 400GB NVMe cache modules. This configuration targets businesses that need immediate, high-density storage for virtualization, backup, or file collaboration without additional integration work.

Sustained Load Behaviour with Dual 10GbE

Dual 10GbE RJ-45 ports provide consistent throughput for multi-user access and replication tasks over long periods, avoiding the bottlenecks seen on single gigabit links. The Xeon six-core CPU and 64GB DDR4 ECC memory maintain responsiveness during concurrent virtual-machine workloads, snapshot operations, and background data-scrubbing. An out-of-band management LAN port keeps monitoring and recovery paths open even when the primary interfaces are saturated.

Expansion Limits and Physical Constraints

A PCIe Gen4 x8 slot and dual M.2 NVMe slots allow cache or networking upgrades, while a compatible expansion unit can extend the system to sixteen drive bays. The 1U chassis measures 44mm high, 481.9mm wide, and 668.5mm deep, weighing 9.5kg, so it fits standard racks but requires adequate front-to-rear airflow within the 5°C to 35°C operating range. Buyers needing more than four internal bays or additional PCIe cards must plan for the expansion unit and rack space accordingly.
