Synology RS3626xs Intel Xeon D-1726 12-Bay Rackmount NAS 8GB RAM 1.6TB Cache 144TB Drives

Enterprise 12-Bay Rackmount NAS

The Synology RS3626xs is a 2U rackmount network-attached storage server built for businesses that need high-capacity, centralized file storage and data protection. It arrives fully assembled and tested with twelve 12 TB enterprise drives providing 144 TB of raw capacity, plus 1.6 TB of SSD cache. A 6-core Intel Xeon D-1726 processor and 8 GB of DDR4 ECC memory handle virtualization, surveillance, and multi-site collaboration workloads. Redundant power supplies protect service availability from a single power-supply failure.

Upgrade from Slower Network or Smaller Arrays

This system replaces older NAS units limited to 1 GbE links or fewer drive bays when your team needs faster data access and room to grow. The jump is worth it when workloads demand sustained throughput above what gigabit Ethernet can deliver, or when you must consolidate multiple smaller volumes into a single 144 TB pool. Two integrated 10GbE RJ-45 ports support Link Aggregation for increased bandwidth, load balancing, and network failover. Synology reports sequential performance exceeding 6,300 MB/s read and 3,700 MB/s write under its test conditions.

Verify Rack Space, Power, and Expansion Needs

Confirm your rack can accommodate a 2U chassis measuring 88 mm high, 482 mm wide, and 724 mm deep, weighing 14.5 kg. Ensure 100-240 VAC 50/60 Hz power is available for the dual C13 to C14 cords. The operating environment must stay within 0°C to 35°C and 8% to 80% relative humidity. Two PCIe Gen 4 x8 slots are open for future 10GbE, 25GbE, Fibre Channel, or additional cache cards. Memory can be expanded to 48 GB if applications require more than the installed 8 GB.
