12-Bay Xeon D-1726 NAS for Enterprise Workloads
The Synology RS3626xs is a 2U rackmount storage server with twelve drive bays, a six-core Intel Xeon D-1726 processor and 48GB of DDR4 ECC memory. It arrives fully assembled with twelve 4TB enterprise SATA drives for 48TB raw capacity. Dual 10GbE RJ-45 ports and an out-of-band management LAN port are integrated.
Suited for Centralised File.
Organisations needing a single box for file sharing, backup, virtual machines and IP camera recording will match the CPU, memory and 10GbE throughput. Buyers who need 25GbE or Fibre Channel connectivity must add compatible expansion cards through the two PCIe slots. Sites without rack infrastructure should choose a tower form factor instead.
Twelve 3.5-Inch SATA Bays Define Maximum Drive Count
The chassis accepts exactly twelve 3.5-inch SATA HDDs or 2.5-inch SATA SSDs; no additional internal bays exist. Expansion beyond 48TB raw requires external Synology expansion units. This bay count is the hard limit for internal storage growth.

Questions about this item
What real-world throughput can I expect from the two 10GbE ports under load?
Synology reports sequential speeds above 6,300 MB/s read and 3,700 MB/s write under its test conditions, and the two ports support link aggregation for higher bandwidth and failover.
What network speeds do the onboard RJ-45 ports actually negotiate?
The unit provides two 10GBASE-T RJ-45 ports and a dedicated out-of-band management port; each 10GbE port auto-negotiates down to 1 GbE or 100 MbE if the switch requires it.
How much rack depth does the 2U chassis need for the drives and cables?
The chassis measures 482 mm wide, 88 mm high and 724 mm deep, so allow at least 724 mm of usable rack depth plus clearance for rear cables and airflow.
