12-Bay Rackmount NAS for Enterprise Storage
The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need high-capacity, centralised file storage and data protection. It arrives fully assembled and tested with twelve 24TB enterprise drives delivering 288TB of raw capacity. The platform targets virtualisation, surveillance and multi-site collaboration workloads.
Xeon D-1726 Processor with 8GB DDR4 ECC
A 6-core Intel Xeon D-1726 CPU and 8GB of DDR4 ECC memory, expandable to 48GB, provide the compute foundation for demanding business applications. Dual 10GbE RJ-45 ports support Link Aggregation for bandwidth scaling and network failover. Synology reports sequential performance exceeding 6,300 MB/s read and 3,700 MB/s write under its test conditions.
Redundant Power and PCIe Gen 4 Expansion
Redundant power supplies protect service availability from a single power-supply failure. Two PCIe Gen 4 x8 slots accept compatible 10GbE or 25GbE adapters, Fibre Channel cards or additional SSD caching hardware. The chassis accepts twelve 3.5-inch SATA HDDs or 2.5-inch SATA SSDs and operates from 100-240 VAC at 50/60Hz.

Questions about this item
How does the 6300 MB/s sequential read figure translate to daily file access on this RS3626xs?
Synology measured that read rate under its own test conditions using the integrated 10GbE ports and the installed enterprise drives; real-world throughput will depend on your network layout, client mix and workload type.
What does the two 10GbE RJ-45 ports actually limit in a production network?
Each port caps at 10 Gb/s; Link Aggregation can combine them for higher aggregate bandwidth, load balancing and failover, but single-stream transfers cannot exceed one 10GbE link.
What physical space and mounting hardware does the 12-bay unit require?
The chassis measures 88 mm high, 482 mm wide and 724 mm deep, weighs 14.5 kg, and ships with a front cover plus an accessory pack for rack installation.
