Ready-to-Run 4-Bay Rackmount NAS
The Synology RS1626xs+ arrives fully assembled with 32GB DDR4 ECC memory, a 2-port 25GbE SFP28 adapter and four 16TB Synology Enterprise drives for 64TB raw capacity. A 6-core Intel Xeon D-1726 processor powers virtualization, backup and file services in a 1U chassis that fits standard racks.
Upgrade From Slower Network Or Smaller Arrays
Dual 10GbE RJ-45 ports and the included 25GbE card remove the 1GbE bottleneck that limits older NAS units, while the 64TB drive set replaces multi-volume sprawl with a single protected pool. The PCIe Gen4 x8 slot and dual M.2 NVMe cache bays let you add speed or capacity later without a forklift migration.
Suits Teams Needing High Throughput Now
IT groups that want immediate 25GbE performance and enterprise drives without staging hardware will benefit. Buyers who need more than four drive bays in the main unit, or who require a different drive vendor, should look at a configuration that matches those constraints.

Questions about this item
What rack depth does the 44 mm high RS1626xs+ require?
The unit measures 481.9 mm wide by 668.5 mm deep and fits a standard 1U rack space; allow extra depth for cables and airflow.
Which PCIe slot accepts the included 2-port 25GbE adapter?
Install the Synology 2-port 25GbE adapter in the PCIe Gen4 x8 expansion slot; the common mistake is seating it in the M.2 NVMe SSD slots instead.
How many 16TB enterprise drives can be swapped later without tools?
All four front-accessible bays hold 16TB Synology Enterprise NAS drives and support hot-swap replacement.
