Ready-to-run 12-bay rack NAS
The Synology RS3626xs arrives fully assembled with twelve 4 TB enterprise drives, a 1.6 TB dual-drive cache set, and 8 GB of DDR4 ECC memory. A 6-core Intel Xeon D-1726 processor powers file storage, virtualization and surveillance workloads in a 2U form factor.
Dual 10GbE and PCIe Gen 4 expansion
Two built-in 10GbE RJ-45 ports support link aggregation and failover, while two PCIe Gen 4 x8 slots accept additional network or caching cards. Redundant power supplies protect uptime if one unit fails, and the web-based manager handles DHCP configuration.
Rated for 0–35 °C operation
The chassis draws 100–240 VAC and operates within 8–80 % relative humidity. Synology quotes sequential throughput above 6,300 MB/s read and 3,700 MB/s write under its test conditions, indicating sustained performance within the specified thermal envelope.

Questions about this item
How much RAM can the Xeon D-1726 system address before the memory limit is reached?
The installed 8 GB of DDR4 ECC memory is configurable to 48 GB, so the processor supports up to 48 GB total.
What are the steady-state power and thermal figures when the unit runs continuously at full load?
The power supply accepts 100-240 VAC at 50/60 Hz and the operating temperature range is 0°C to 35°C; no specific sustained power-draw or acoustic numbers are published.
Which drive interfaces and form factors must already be available in the rack for the twelve installed drives to operate?
The twelve 4 TB Synology Enterprise NAS drives are 3.5-inch SATA HDDs that occupy the twelve front-accessible drive bays of the 2U chassis.
