Synology RS3626xs 12-Bay Rackmount NAS
The Synology RS3626xs is a 2U rackmount network-attached storage server built for enterprise environments. It ships fully assembled with an Intel Xeon D-1726 processor, 16GB of DDR4 memory, 3.2TB of enterprise SSD cache, and twelve 4TB enterprise hard drives providing 48TB of raw capacity.
Installation and common issues
The unit arrives pre-configured and tested, so initial setup focuses on rack mounting and network integration. Two 10GbE RJ-45 ports and an out-of-band management LAN port simplify connectivity, while redundant power supplies reduce downtime risk. Builders without 10GbE infrastructure will not utilise the full network potential, and the fixed 16GB memory may limit heavy virtualization workloads.
Capacity headroom and limits
Twelve drive bays filled with 4TB drives deliver 48TB raw storage, supplemented by 3.2TB of high-speed cache for frequent data access. Sequential throughput exceeds 6,300 MB/s read and 3,700 MB/s write under test conditions. Two PCIe Gen 4 x8 slots allow future addition of faster networking or extra cache, but the installed drive set defines the immediate capacity ceiling.

What ships with the unit and what must I source separately?
The box contains the 12-bay main unit, accessory pack, two C13-to-C14 power cords and the front cover; drives, cache modules and RAM are already installed, so no extra components are required for basic operation.
