A 4-bay rackmount NAS with AMD Ryzen processor, 16GB DDR4 memory, 800GB cache and 16TB of Synology Plus drives, fully assembled and tested
The Synology RS826+ is a 1U rackmount NAS built for edge locations, remote offices, and growing business storage environments. It runs on a 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor with 16GB of DDR4 ECC memory installed. Four drive bays hold the included 16TB of Synology Plus NAS drives. A PCIe Gen3 slot allows future 10GbE or 25GbE adapter upgrades.
The unit operates within a 0°C to 35°C temperature range and 5% to 95% relative humidity. It draws power from a 100-240 VAC 50/60Hz supply. The compact 44 mm × 480 mm × 492.6 mm chassis weighs 6.4 kg. Four integrated 1GbE RJ-45 ports support Link Aggregation for load balancing and automatic failover during sustained workloads.
This configuration adds 800GB of Synology Enterprise cache via two 400GB modules alongside the four 4TB Synology Plus NAS drives. The system arrives fully assembled and tested, eliminating initial setup time. Two USB 3.2 Gen 1 ports provide direct-attached peripheral connectivity. Management is handled through a web-based interface with DHCP client support.

Mount the 1U chassis using the included accessory pack; the step often missed is connecting all four 1GbE RJ-45 ports to enable Link Aggregation for load balancing and failover.
The four 4TB Synology Plus drives and two 400GB Enterprise Cache modules are the only field-replaceable components; memory can be expanded to 32GB DDR4 ECC if required.
The four 1GbE RJ-45 ports cap throughput before the AMD Ryzen V1500B processor or 16GB DDR4 memory become bottlenecks.
