12-bay rackmount NAS with Xeon D-1726
The Synology RS3626xs is a 2U rackmount network-attached storage server built around a 6-core Intel Xeon D-1726 processor. It ships fully assembled with 16GB of DDR4 ECC memory and twelve 16TB enterprise drives for 192TB of raw capacity. This configuration targets businesses that need centralised file storage, virtualisation support and multi-site collaboration from day one.
Two integrated 10GbE ports and PCIe Gen 4 expansion
Network connectivity relies on two RJ-45 10GbE LAN ports that support link aggregation for higher throughput and failover. Synology quotes sequential reads above 6,300 MB/s and writes above 3,700 MB/s under its own test conditions. Two PCIe Gen 4 x8 slots allow the addition of compatible 25GbE adapters, Fibre Channel cards or SSD caching modules when workloads demand more bandwidth or IOPS.
Verify rack space, power and memory ceiling
The unit measures 88 mm high, 482 mm wide and 724 mm deep, weighing 14.5 kg, so confirm your rack depth and weight allowance before ordering. It operates on 100-240 VAC with dual C13-to-C14 cords for redundant supply. Installed memory is 16GB DDR4 ECC with a maximum of 48GB; buyers planning heavier virtualisation should check whether the cap meets their workload.

Questions about this item
Should I pick the 16 GB DDR4 configuration or the 48 GB DDR4 maximum for virtualization workloads?
The unit ships with 16 GB of DDR4 ECC memory and supports expansion up to 48 GB; choose 48 GB if you plan to run multiple virtual machines or heavy caching workloads.
What does the quoted 6,300 MB/s sequential read mean when the NAS is serving files over the network?
That figure comes from Synology internal tests; real-world throughput over the two 10GbE RJ-45 ports will be limited by the 10 Gb/s network link and client performance.
How do the two 10GbE RJ-45 ports and PCIe Gen 4 x8 slots constrain expansion options?
The integrated 10GbE ports support link aggregation and failover, while the two PCIe Gen 4 x8 slots accept compatible 10GbE, 25GbE, Fibre Channel or SSD caching cards for future bandwidth upgrades.
