Ready-to-deploy 4-bay NAS

The Synology RS1626xs+ arrives fully assembled with an Intel Xeon D-1726 processor, 64GB of DDR4 ECC memory, 3.2TB of NVMe cache across two drives and four 4TB enterprise hard drives. It occupies a single rack unit and includes dual 10GbE RJ-45 ports plus a dedicated management link.

Suited for virtualization and heavy file workloads

Teams that need immediate capacity for virtual machines, large-scale backup or collaborative editing will benefit from the pre-installed cache and storage. Buyers who require more than four internal drive bays or a different processor class should evaluate other platforms.

Dual 10GbE networking decides fit

Two built-in 10GbE RJ-45 ports provide high-throughput connectivity without an add-in card; if the environment only offers 1GbE switching the extra bandwidth will not be used.

Questions about this item

How much power does the RS1626xs+ draw from a 100-240 VAC 50/60Hz supply when running continuously?

The unit operates on 100-240 VAC at 50/60 Hz and is rated for an ambient temperature range of 5°C to 35°C during continuous operation.

Which drives and memory are required to populate the four bays and reach the 64GB DDR4 capacity?

Four 4TB Synology Enterprise NAS drives fill the 3.5-inch bays, while 64GB of Synology DDR4 ECC RDIMM memory occupies the DIMM slots.

Can the dual 10GbE RJ-45 ports and PCIe Gen4 x8 slot work with my existing 1GbE switches and older expansion cards?

The two 10GbE RJ-45 ports auto-negotiate down to 1GbE, and the PCIe Gen4 x8 slot is backward-compatible with Gen3 and Gen2 cards.
