Twelve-bay 2U rackmount NAS with Xeon D-1726 processor, 48GB DDR4 ECC memory, dual 25GbE SFP28 plus dual 10GbE RJ-45 ports, and 96TB of Synology Enterprise drives pre-installed
The Synology RS3626xs arrives fully assembled with twelve 8 TB enterprise SATA drives for 96 TB raw capacity, a 6-core Xeon D-1726 processor and 48 GB DDR4 ECC memory. Dual redundant power supplies and a 2-port 25 GbE SFP28 adapter are installed and tested. It targets IT teams that need immediate, high-throughput file, backup or virtualization storage without a build step.
The dual 10 GbE RJ-45 ports and 25 GbE uplinks serve environments that move large datasets across the LAN, while the 12-bay chassis supports mixed 3.5-inch HDD and 2.5-inch SSD populations. Teams that need more than twelve drive slots, GPU compute, or direct Fibre Channel attachment will need a different platform. Operating temperature is rated 0 °C to 35 °C.
Twelve Synology 8 TB drives fill every bay, delivering the full 96 TB figure at shipment. The Xeon D-1726 and 48 GB DDR4 ECC memory provide the compute headroom for RAID management, snapshots and virtual machines. Expandability is limited to the two PCIe Gen 4 x8 slots for additional network or cache cards.

The twelve 8TB Synology Enterprise NAS drives are the primary wear items; plan to swap any that report SMART errors or exceed rated workload limits.
Operating temperature tops out at 35°C; beyond that the system throttles to protect the Xeon D-1726 and DDR4 memory.
Redundant power supplies and multiple fans keep the Xeon D-1726 within its 35°C limit; expect noticeable but data-centre-typical fan noise at full tilt.
