Enterprise 4-Bay Rackmount NAS
The Synology RS1626xs+ is a 1U rackmount NAS powered by an Intel Xeon D-1726 processor with 32GB of installed DDR4 memory. It arrives fully assembled with 80TB of raw storage across four 20TB Synology Enterprise drives and 1.6TB of NVMe cache on two 800GB modules. Dual 10GbE RJ-45 ports and a dedicated management LAN provide high-throughput connectivity for demanding workloads.
Suited for virtualization and heavy file workloads
This unit serves businesses that need consolidated block and file storage with hardware-accelerated cache for latency-sensitive applications. The four-bay chassis limits internal expansion without an additional Synology expansion unit, so buyers who require more than four drives inside the same appliance should look at larger chassis options.
Four drive bays with dual 10GbE
The 4-bay form factor and two 10GbE RJ-45 interfaces determine how much data can be stored locally and how fast it moves across the network. Match these constraints to your capacity growth plan and network backbone before deployment.

Questions about this item
How long can the Xeon D-1726 sustain full load before thermal throttling?
The RS1626xs+ is rated for continuous operation between 5°C and 35°C ambient, with the 1U chassis and dual power cords designed to keep the Xeon D-1726 within thermal limits during sustained 10GbE and NVMe cache workloads.
What is the typical power draw and fan noise when the unit runs 24/7 with all four 20TB drives and 1.6TB NVMe cache active?
The power supply accepts 100-240 VAC at 50/60 Hz and the 9.5 kg chassis uses temperature-controlled fans; acoustic output varies with load but stays within Synology's 1U rackmount specifications for data-centre environments.
Which expansion unit and cable are required to grow beyond the four internal bays?
A compatible Synology expansion unit connects through the PCIe Gen4 x8 slot, allowing the RS1626xs+ to scale up to 16 total drives for additional capacity beyond the included 80TB.
