Ready-to-run 4-bay rackmount NAS

The Synology RS1626xs+ arrives fully assembled with an Intel Xeon D-1726 processor, 32 GB of DDR4 memory, 800 GB of NVMe cache and 48 TB of enterprise drives installed. It occupies a single 1U rack space and includes dual 10 GbE RJ-45 ports plus a dedicated management LAN connection. The unit is tested and configured for immediate deployment in business environments.

Suited for virtualization

Organizations that need consolidated storage for virtual machines, backup targets or collaborative workloads will benefit from the integrated cache and high-speed networking. Buyers who require more than four internal drive bays or who need Fibre Channel connectivity should evaluate alternative platforms.

Four drive bays with expansion capability

The chassis provides four 3.5-inch bays populated with 12 TB enterprise drives and supports additional capacity through a compatible Synology expansion unit. This bay count determines the maximum internal raw storage before adding external enclosures.

Questions about this item

How often do the 400GB NVMe cache modules need replacement?

Synology Enterprise NVMe cache modules are rated for heavy write workloads; typical replacement aligns with the drive endurance cycle rather than a fixed schedule.

Which component hits its limit first during sustained 10GbE transfers?

The 10GbE RJ-45 ports saturate before the Xeon D-1726 CPU or 32GB DDR4 memory under continuous high-throughput loads.

What is the power draw and heat output when all four 12TB drives and cache run 24/7?

The unit operates on 100-240 VAC 50/60Hz within a 5°C to 35°C range; sustained loads stay inside this thermal envelope.
