Enterprise 12-bay rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need centralised file storage, virtualisation and backup in a single validated appliance. It arrives fully assembled with twelve 4 TB enterprise drives, 8 GB of DDR4 ECC memory and 3.2 TB of SSD cache.

10GbE networking limits

Two integrated 10GbE RJ-45 ports provide high-throughput connectivity and support link aggregation for load balancing and failover. Sequential throughput reaches 6,300 MB/s read and 3,700 MB/s write under Synology test conditions. Two PCIe Gen 4 x8 slots allow future 25GbE or Fibre Channel adapters.

48 TB raw capacity

The chassis holds twelve 3.5-inch SATA drives delivering 48 TB raw capacity out of the box. Expansion units can increase the total bay count, but the base unit is limited to these twelve bays. Buyers who need more than 48 TB without adding expansion hardware should consider a larger platform.

Questions about this item

Should I choose the 8GB memory model or upgrade to the maximum 48GB capacity?

The unit ships with 8GB DDR4 ECC RAM and supports expansion to 48GB total for heavier virtualization or multi-user workloads.

What do the 6300 MB/s read and 3700 MB/s write figures mean for daily file transfers?

Those are Synology sequential benchmarks under test conditions; real-world SMB or iSCSI speeds will be lower and depend on drive mix, RAID type, and network path.

How do the two built-in 10GbE RJ-45 ports limit total network throughput?

Each port runs at 10GbE line rate; Link Aggregation can combine them for load balancing and failover, but a single stream still caps at one 10GbE link.
