4-bay enterprise rack NAS

The Synology RS1626xs+ is a 1U rackmount network-attached storage server built for businesses that require high-throughput file services, virtualization hosting and backup consolidation. It ships fully assembled with an Intel Xeon D-1726 processor, 16GB DDR4 ECC memory and four 20TB enterprise drives delivering 80TB raw capacity.

Dual 10GbE and expansion slot

Two onboard 10GbE RJ-45 ports provide high-speed LAN connectivity without extra cards, while a dedicated out-of-band management port keeps administration separate. A PCIe Gen4 x8 slot and dual M.2 NVMe slots allow cache or networking upgrades, and a compatible expansion unit can extend the system to sixteen drive bays.

80TB raw with 64GB memory ceiling

The installed 80TB array handles large media libraries, VM datastores and multi-site replication workloads. Memory can be expanded to 64GB for heavier virtualization or deduplication tasks. Builds that need more than four drives or higher single-thread performance will require a larger chassis or a different processor class.

Questions about this item

What is the first thermal limit the RS1626xs+ hits during sustained workloads?

The operating temperature range tops out at 35°C, so sustained heavy loads will reach that ceiling before any other limit.

How much noise and heat does the 9.5 kg 1U chassis produce when running 24/7?

Dual 10GbE ports, dual M.2 NVMe slots and a PCIe Gen4 x8 slot draw continuous power, so the twin fans run steadily and exhaust measurable heat into the rack.

Which drives must already be installed for the 80TB array to work out of the box?

Four 20TB Synology Enterprise NAS drives come pre-fitted, so no additional drives are required to start using the full capacity.
