Synology RS1626xs+ 4-bay rackmount NAS

The Synology RS1626xs+ is a 1U enterprise rackmount NAS with four drive bays. It ships fully assembled with an Intel Xeon D-1726 processor, 64GB DDR4 memory, 3.2TB NVMe cache and 48TB of Synology enterprise drives installed.

Suits virtualization and backup.

This unit suits businesses running virtual machines, high-speed file sharing or backup workloads that benefit from dual 10GbE ports and NVMe cache acceleration. Organisations needing more than four internal bays without adding an expansion unit should consider a different chassis.

Four drive bays define internal capacity

The RS1626xs+ provides four 3.5-inch bays populated with 12TB enterprise drives for 48TB raw storage. Adding a compatible Synology expansion unit is the only way to increase the number of installed drives beyond four.

Questions about this item

When will the four 12TB Synology Enterprise drives need replacement?

The 48TB array uses four 12TB Synology Enterprise NAS drives rated for continuous operation; plan replacement when SMART health indicators degrade or after the manufacturer-rated service life.

What limits sustained write throughput on the 3.2TB cache?

The 3.2TB cache consists of two 1.6TB Synology Enterprise NVMe modules; sustained writes are limited by the PCIe Gen4 x8 lane bandwidth and the drive endurance rating.

How loud and hot does the 1U chassis get under 24/7 load?

Operating temperature range is 5°C to 35°C; the 1U rackmount uses internal fans that ramp with CPU and drive load, producing typical data-centre noise levels.
