Purpose-built enterprise storage

The Synology RS1626xs+ is a 1U rackmount NAS equipped with an Intel Xeon D-1726 processor and 64GB of DDR4 memory. It ships fully assembled with four 12TB enterprise drives for 48TB of raw capacity. The platform targets businesses that need virtualization, backup and file collaboration in a compact form factor.

Sustained workload behaviour

Dual 10GbE RJ-45 ports and a dedicated management link keep throughput steady during long backup windows or multi-user file access. The Xeon six-core CPU maintains consistent performance for virtual machines and snapshot operations without throttling. Two M.2 NVMe slots and a PCIe Gen4 x8 slot allow cache or networking upgrades as demand grows.

Thermals noise and power

The unit operates between 5°C and 35°C with humidity up to 80% RH, drawing power from a 100-240 VAC 50/60Hz supply. Its 44 mm height and 9.5 kg weight fit standard racks while the front cover directs airflow across the drive bays. LEDs for power, drive status and network link give immediate visual feedback during normal operation.

Questions about this item

How much heat does the RS1626xs+ generate when running 24/7?

The unit operates between 5°C and 35°C and draws 100-240 VAC at 50/60 Hz, so sustained use stays within that thermal envelope.

Which drives or expansion units must I already own to populate the four bays?

Four 12 TB Synology Enterprise NAS drives are already installed, so no additional drives are required for the internal bays.

Will the dual 10GbE RJ-45 ports work with my existing 1 GbE switches and cabling?

Yes, the 10GbE ports auto-negotiate down to 1 GbE, letting you use current Cat5e or Cat6 infrastructure immediately.
