Synology RS3626xs 12-Bay Enterprise NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity centralised file storage, virtualisation support, and multi-site collaboration. It ships fully assembled with a 6-core Intel Xeon D-1726 processor, 48 GB of DDR4 ECC memory, and twelve 8 TB Synology enterprise drives pre-installed for a total of 96 TB raw capacity. Redundant power supplies help maintain service availability if one unit fails.

Network Limits of Integrated 10GbE Ports

Two onboard 10GbE RJ-45 ports provide up to 10 Gbps per link and support Link Aggregation for combined throughput, load balancing, and automatic failover. Synology quotes sequential read performance above 6,300 MB/s and write performance above 3,700 MB/s under its test conditions, but actual speeds depend on your switch, cabling, and client workload. The single out-of-band management port uses a separate 1 GbE connection for remote administration.

Compatibility Checks Before Ordering

Verify that your rack provides a 2U slot with at least 724 mm depth and can support 14.5 kg of equipment weight. Confirm 100-240 VAC power availability with two C13 outlets for the redundant supplies. Ensure your network infrastructure includes 10GbE-capable switches and Cat 6a or better cabling to utilise the integrated ports. Expansion beyond the twelve internal bays requires compatible Synology expansion units and available PCIe Gen 4 x8 slots for additional network or caching cards.

Questions about this item

Should I pick the 48 GB RAM and 96 TB drive bundle or look for a different capacity?

The unit ships with 48 GB DDR4 memory and twelve 8 TB SATA drives for 96 TB raw capacity.

What do the 6,300 MB/s read and 3,700 MB/s write figures mean once the NAS is in production?

Those are Synology sequential benchmarks under test conditions; real-world throughput depends on workload, RAID level and network topology.

How do the two 10GbE RJ-45 ports and PCIe Gen 4 x8 slots limit actual network speed?

Each 10GbE port caps at 10 Gb/s; the two PCIe Gen 4 x8 slots can accept faster adapters such as 25GbE cards for higher ceiling.
