Ready-to-run 4-bay rack NAS

The Synology RS1626xs+ arrives fully assembled with 32GB DDR4 ECC memory and four 12TB enterprise drives for 48TB raw capacity. An Intel Xeon D-1726 six-core processor handles virtualization, file sharing, backup and surveillance workloads in a 1U form factor. Web-based DSM management provides snapshot, replication and hybrid-cloud tools out of the box.

Dual 10GbE plus PCIe Gen4 expansion

Two 10GbE RJ-45 ports and a dedicated 1GbE management link connect directly to high-speed switches without extra cards. Front-access drive bays support hot-swap replacement while dual M.2 NVMe slots and a PCIe Gen4 x8 slot remain free for cache or networking upgrades. Redundant C13/C14 power cords and a 5–35 °C operating range suit standard rack environments.

Scales to 16 bays with expansion unit

The platform grows by attaching a compatible Synology expansion unit, raising maximum drive count to 16 for capacity-heavy archives. Memory can be increased to 64GB when workloads demand more VMs or larger caches. Buyers needing more than four drives today or fibre-channel connectivity should evaluate larger chassis instead.

Questions about this item

How fast are the two built-in 10GbE RJ-45 ports in practice?

They run at up to 10 gigabits per second and handle the RS1626xs+ network traffic directly from the Xeon D-1726 processor.

What rack depth and rail type does the 1U chassis require?

The unit measures 44 mm high, 481.9 mm wide and 668.5 mm deep, so it needs a standard 1U slot and rails that support at least 668.5 mm depth.

How are the four 12TB Synology Enterprise NAS drives installed, and what step is often missed?

The drives come pre-installed in the four bays; the step people miss is confirming the DSM storage pool is created and the volume is initialised before writing data.
