Enterprise 4-Bay Rackmount NAS
The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for businesses that need consolidated file sharing, backup, virtualization and surveillance in a single appliance. It ships fully assembled with an Intel Xeon D-1726 six-core processor, 16GB DDR4 ECC memory, four 12TB enterprise drives for 48TB raw capacity and a 1.6TB NVMe cache tier.
Dual 10GbE and Expansion Limits
Network connectivity relies on two onboard 10GbE RJ-45 ports plus a dedicated 1GbE management link, so throughput tops out at 10GbE unless a PCIe Gen4 x8 card adds faster interfaces. The chassis holds only four drives internally; reaching the 16-drive maximum requires a compatible Synology expansion unit, and the two M.2 slots are already occupied by the installed cache SSDs.
48TB Raw with NVMe Acceleration
The included 48TB of enterprise HDD storage handles large file repositories, backup targets and virtual-machine datastores, while the 1.6TB NVMe read-write cache absorbs bursty metadata and small-block I/O. Memory caps at 64GB, so workloads needing more RAM or more than four internal drives will outgrow the base unit without expansion hardware.
