12-bay Xeon D-1726 NAS with 96 TB drives
The Synology RS3626xs is a 2U rackmount NAS populated with twelve 8 TB enterprise drives for 96 TB of raw capacity. A 6-core Intel Xeon D-1726 processor and 32 GB of DDR4 ECC memory handle virtualization, surveillance and multi-site collaboration workloads. Redundant power supplies protect service availability against a single supply failure.
Factory cache and expansion slots
Two 800 GB Synology enterprise SSDs provide 1.6 TB of read-write cache to accelerate frequent data access. Two PCIe 4.0 x8 slots remain open for compatible 10GbE or 25GbE adapters, Fibre Channel cards or additional SSD caching hardware. The system ships fully assembled and tested so it is ready for rack deployment.
10GbE limits and thermal range
Dual onboard 10GbE RJ-45 ports support Link Aggregation for bandwidth scaling and failover, but throughput is bounded by the 10 Gb/s electrical interface. Sequential benchmarks cite 6 300 MB/s read and 3 700 MB/s write under vendor test conditions. Operating temperature is rated 0 °C to 35 °C, so sustained loads require adequate rack airflow.

Questions about this item
How often should the 1.6TB enterprise cache be checked or replaced?
Synology Enterprise cache modules are rated for heavy write workloads; monitor SMART health via DSM and replace only when the drive reports end-of-life.
What limits sustained throughput first, the 10GbE ports or the Xeon D-1726?
The two 10GbE RJ-45 ports cap at 10Gbps each, so network bandwidth reaches its ceiling before the 6-core Xeon D-1726 saturates.
How loud and hot does the 2U chassis get with twelve 8TB drives running 24/7?
Operating range is 0°C to 35°C; dual redundant fans keep drive temps in spec, and idle noise is typical for a rackmount 2U server.
