Enterprise 4-Bay Rackmount NAS

The Synology RS1626xs+ is a 1U rackmount network-attached storage server powered by an Intel Xeon D-1726 processor and equipped with 64GB of DDR4 memory. It arrives fully assembled with four 8TB enterprise drives providing 32TB of raw capacity and a dual-port 10GbE adapter installed. The platform targets businesses that require high-performance file sharing, virtualization, backup and surveillance storage in a compact form factor.

Build Integration

The unit occupies a single rack unit and connects through two 10GbE RJ-45 ports plus a dedicated out-of-band management LAN port. Two USB 3.2 Gen 1 ports and an internal PCIe Gen4 x8 slot allow additional peripherals or expansion cards, while dual M.2 NVMe slots support cache acceleration. A compatible Synology expansion unit can extend the drive count beyond the four internal bays. Redundant C13 to C14 power cords and a 100-240 VAC supply simplify rack power distribution.

Target Audience

This configuration suits IT teams that need a turnkey, high-throughput NAS with ECC memory and 10GbE connectivity ready for immediate deployment. Organizations seeking direct-attached storage, desktop-form-factor appliances or single-drive redundancy should evaluate alternative product lines. Buyers requiring more than four internal drive bays without adding an expansion chassis will also need a different platform.

Questions about this item

What CPU thermal limit does the Intel Xeon D-1726 hit first under sustained load?

The processor is rated for operation up to 35 °C ambient; sustained heavy workloads will reach that thermal boundary before any other component limit.

How much fan noise and heat does the 1U chassis produce when the RS1626xs+ runs 24/7 with all four 8 TB drives active?

The 44 mm high rackmount unit draws 100-240 VAC and operates within 5 °C to 35 °C; continuous operation keeps internal temperatures in that range with standard server-room airflow.

Which expansion unit must I already own to grow the RS1626xs+ beyond its four internal bays?

A compatible Synology expansion unit connects via the rear PCIe Gen4 x8 slot to scale the system up to 16 total drives.
