Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity, centralised file storage and data protection. It ships fully assembled with twelve 16 TB enterprise drives for 192 TB raw capacity, a six-core Intel Xeon D-1726 processor and 16 GB of DDR4 ECC memory. This configuration suits virtualisation, surveillance and multi-site collaboration workloads.

Dual 10GbE and PCIe Expansion Limits

Two integrated 10GbE RJ-45 ports support link aggregation for higher throughput and network failover, with sequential performance rated at 6 300 MB/s read and 3 700 MB/s write under vendor test conditions. Two PCIe Gen 4 x8 slots accept compatible 10GbE, 25GbE or Fibre Channel adapters and SSD caching cards, but the chassis provides no additional drive bays beyond the twelve front-access slots.

Pre-Assembled Installation and Drive Compatibility

The unit arrives tested and populated, so initial setup only requires rack mounting, power and network cabling, then the web-based management wizard. Twelve 3.5-inch SATA hard drives or 2.5-inch SATA SSDs are supported; other form factors or interfaces cannot be used in the native bays. Redundant power supplies reduce downtime risk from a single supply failure.

Questions about this item

Should I choose the 12-bay 192TB configuration or look for a smaller capacity?

This unit ships fully populated with twelve 16TB enterprise drives for 192TB raw capacity in a 2U rackmount form factor.

What do the 6300 MB/s read and 3700 MB/s write figures mean once the RS3626xs is in production?

Those are Synology's sequential throughput numbers under test conditions using the integrated 10GbE ports and the installed Xeon D-1726 processor.

How does the 10GBASE-T interface cap real-world transfer speeds on this NAS?

The two onboard 10GbE RJ-45 ports limit single-stream transfers to the 10GbE line rate, while Link Aggregation can combine both ports for higher aggregate throughput.
