12-Bay Rackmount NAS for Enterprise Workloads

The Synology RS3626xs is a 2U rackmount storage server built for organisations that need high-capacity, centrally managed file services, virtualization support and surveillance storage in a single appliance. It arrives fully assembled with twelve enterprise-class drives and cache modules installed and tested.

Intel Xeon D-1726 6-Core Processor

A 6-core Intel Xeon D-1726 CPU provides the compute foundation for multi-user file access, container workloads and backup tasks. The system includes 16 GB of DDR4 ECC memory, expandable to 48 GB, ensuring data integrity for critical business datasets.

Sustained Sequential Throughput Over 6 300 MB/s Read

Synology reports sequential read performance exceeding 6 300 MB/s and write performance above 3 700 MB/s under test conditions, reflecting sustained throughput for large-file workflows rather than brief burst speeds. Redundant power supplies and two 10GbE ports with link aggregation maintain availability during extended heavy load.

Questions about this item

What does the 6300 MB/s sequential read figure mean once the RS3626xs is in a real machine?

Synology reports that figure under its own test conditions; actual throughput will depend on drive mix, RAID type, workload pattern and network path.

What does the two 10GbE RJ-45 ports cap in practice?

Each port runs at up to 10 Gb/s; Link Aggregation can combine them for load balancing and failover.

What does the 2U, 12-bay chassis physically need to fit or mount?

It occupies 2U of rack space measuring 88 mm high, 482 mm wide and 724 mm deep and weighs 14.5 kg.
