Enterprise 12-bay rackmount NAS
The Synology RS3626xs is a 2U rackmount network-attached storage server built for organisations that need centralised file storage, virtualization hosting, and multi-site collaboration. It ships fully assembled with twelve 16 TB enterprise drives, 1.6 TB of SSD cache, and 8 GB of DDR4 ECC memory.
Capacity and headroom
Raw capacity totals 192 TB across twelve 3.5-inch SATA bays, while the 1.6 TB cache tier accelerates frequent workloads. Sequential throughput reaches 6,300 MB/s read and 3,700 MB/s write under vendor test conditions, and memory can be expanded to 48 GB for larger virtualization environments.
Thermals noise and power
The unit operates from 0 °C to 35 °C with redundant 100–240 VAC power supplies that maintain uptime during a single supply failure. Dual 10GbE RJ-45 ports support link aggregation and failover without additional cards, and two PCIe 4.0 x8 slots remain available for future networking or storage upgrades.
