A 1U rackmount NAS with four bays, an AMD Ryzen V1500B processor, 16GB DDR4 memory, 1.6TB cache and 16TB of installed drives
The Synology RS826+ is a 4-bay rackmount NAS powered by a 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor. It arrives with 16GB DDR4 memory installed and supports expansion up to 32 GB. The unit fits a standard 1U rack space and operates from 100-240 VAC 50/60Hz power.
The package includes 1.6TB of Synology Enterprise Cache configured as two 800GB modules plus four 4TB Synology Plus NAS drives for a total of 16TB raw capacity. All components are fully assembled and tested before shipment so the system is ready for immediate deployment. Four 1GbE RJ-45 ports support Link Aggregation for load balancing and failover.
Organisations that want a tested, drive-ready rackmount NAS without manual drive installation or memory configuration will benefit. Buyers who require 10GbE or 25GbE connectivity out of the box must add a compatible PCIe Gen3 adapter themselves. Environments exceeding 35 °C ambient temperature or needing drive bays beyond four should evaluate alternative platforms.

Synology Plus drives are rated for continuous operation; monitor SMART data and replace any drive that shows reallocated sectors or SMART warnings.
The four 1 GbE ports aggregate to roughly 4 Gbps, so sustained transfers above that level will saturate the network link before the CPU or drives hit their limits.
The unit operates between 0 °C and 35 °C; internal fans adjust speed to keep component temperatures in range, producing typical 1U rackmount noise levels.
