A 12-bay rackmount NAS with a Xeon D-1726 processor, 48GB DDR4 RAM, two 10GbE ports, a 25GbE adapter, and 144TB of Enterprise drives pre-installed
The Synology RS3626xs arrives fully assembled with 48GB of DDR4 memory and a 2-port 25GbE adapter installed. Twelve 12TB Synology Enterprise drives provide 144TB of raw capacity out of the box. A 6-core Intel Xeon D-1726 processor handles demanding business workloads including virtualization and multi-site collaboration. Redundant power supplies protect service availability from a single power-supply failure.
Organisations that need high-capacity storage with integrated 10GbE and optional 25GbE connectivity will benefit from the two RJ-45 ports and the pre-installed SFP28 adapter. Two PCIe Gen 4 x8 slots allow further expansion for networking or SSD caching as requirements grow. Buyers who require Fibre Channel connectivity should verify adapter compatibility before purchase. The operating range of 0°C to 35°C limits deployment to controlled environments.
The included drive set delivers 144TB across twelve bays using 3.5-inch SATA HDDs. Sequential read performance exceeds 6300 MB/s and write exceeds 3700 MB/s under vendor test conditions. Link aggregation on the dual 10GbE ports increases bandwidth and provides network failover. The 2U chassis measures 88 mm × 482 mm × 724 mm and weighs 14.5 kg.
