Enterprise 4-Bay Rackmount NAS

The Synology RS1626xs+ is a 1U rackmount network-attached storage server built around an Intel Xeon D-1726 processor. It ships with 64GB of DDR4 memory, 1.6TB of NVMe cache, and four 20TB enterprise drives pre-installed. The unit provides 80TB of raw capacity in a compact 44 mm × 481.9 mm × 668.5 mm chassis weighing 9.5 kg.

Suited For Virtualisation And File Workloads

This system targets organisations that need consolidated block and file storage with integrated snapshot, replication, and backup tools in DSM. Buyers who require more than four drive bays without adding an expansion unit, or who need fibre-channel connectivity, should evaluate alternative platforms.

Pre-Installed Cache And Drives Accelerate Deployment

Two 800GB NVMe cache modules and four 20TB enterprise drives are factory-fitted and validated, eliminating drive-compatibility checks and initial RAID build time. Dual 10GbE RJ-45 ports, a dedicated management LAN, two USB 3.2 Gen 1 ports, and a PCIe Gen4 x8 slot are ready for immediate network and expansion integration.

Questions about this item

Does the Synology RS1626xs+ require any additional drives or expansion units to start using its 80TB of storage?

No, the unit ships fully assembled with four 20TB Synology Enterprise NAS drives installed, providing the full 80TB capacity out of the box.

Can I connect my existing 1GbE network switches directly to the RS1626xs+ without upgrading cabling?

Yes, the dual 10GbE RJ-45 ports auto-negotiate down to 1GbE, so your current Cat5e or Cat6 cables and switches will work immediately.

How can I verify the 1.6TB NVMe cache is active and accelerating volumes after setup?

Open Storage Manager in DSM, select the volume, and confirm the read-write cache status shows the two 800GB Synology Enterprise cache modules as online and healthy.
