Enterprise 4-bay NAS with Xeon D-1726

The Synology RS1626xs+ is a 1U rackmount storage server built for organisations that need high-throughput file services, virtualization hosting or backup targets in a compact form factor. It ships fully populated with four 20 TB enterprise drives and 64 GB of DDR4 ECC memory, so the array is ready for production workloads immediately.

Dual 10GbE and managed thermals

Two 10 GbE RJ-45 ports provide high-speed client connectivity while a dedicated management LAN keeps administration traffic separate. The 100-240 VAC redundant power input supports worldwide deployment and the specified operating range of 5 °C to 35 °C ensures stable operation in standard server rooms without exotic cooling.

Tool-less drive access and expansion ready

The 4-bay front panel allows hot-swap drive replacement without tools, minimising downtime during maintenance. A PCIe Gen4 x8 slot and dual M.2 NVMe slots are available for cache acceleration or additional network cards, while the RS1626xs+ can scale to 16 drives with a compatible Synology expansion unit when capacity needs grow.

Questions about this item

What are the physical steps to mount the Synology RS1626xs+ in a rack, and which step do installers most often overlook?

The unit measures 44 mm high, 481.9 mm wide and 668.5 mm deep, weighing 9.5 kg, so it fits a standard 1U rack space; the step most often missed is securing both C13 to C14 power cords to separate circuits for full redundancy.

Which components in the Synology RS1626xs+ will require replacement or scheduled maintenance over time?

The four 20 TB Synology Enterprise NAS drives are the primary replaceable items; the 64 GB of installed DDR4 memory and the dual M.2 NVMe slots are not user-serviceable parts under normal operation.

What is the first performance limit reached when the Synology RS1626xs+ runs sustained workloads?

The dual 10GbE RJ-45 LAN ports and the PCIe Gen4 x8 expansion slot set the I/O ceiling; once network or expansion bandwidth saturates, the Intel Xeon D-1726 processor and 64 GB DDR4 memory still have headroom.
