Ready-to-deploy enterprise storage

The Synology RS1626xs+ is a 1U rackmount NAS pre-loaded with 64GB of DDR4 ECC memory, 800GB of NVMe cache and 48TB of enterprise drives. It ships fully assembled and tested so IT teams can integrate it into production environments without additional build time.

Suited for virtualization and mixed workloads

Organisations running virtual machines, container clusters or high-throughput file shares will benefit from the six-core Xeon D-1726 and dual 10GbE ports. Buyers who need more than four drive bays or who require fibre-channel connectivity should evaluate alternative platforms.

Six-core Xeon D-1726 processor

The Intel Xeon D-1726 provides the compute headroom for simultaneous backup, surveillance and virtualization tasks while maintaining the low power envelope required for dense rack deployments.

Questions about this item

How often will the four 12TB Synology Enterprise NAS drives need replacement in the RS1626xs+?

The 12TB Synology Enterprise NAS drives are rated for continuous operation; replacement timing depends on workload and SMART health monitoring via DSM.

Which limit appears first when the Xeon D-1726 runs sustained workloads on the RS1626xs+?

The 35 °C maximum operating temperature is the primary environmental limit; thermal throttling may engage before processor or memory ceilings.

What noise and heat levels should I expect from the RS1626xs+ running all day?

The 1U chassis uses internal fans to keep the Xeon D-1726 and four 12TB drives within the 5–35 °C range; acoustic output varies with fan speed under load.
