Synology Inc.
A compact 1U rackmount NAS with four drive bays, 32GB DDR4 memory, 1.6TB enterprise cache and 16TB of Synology Plus drives, powered by a 2.2 GHz AMD Ryzen V1500B processor and four 1GbE ports
The Synology RS826+ arrives as a fully assembled 1U rackmount NAS with four drive bays populated by 4TB Synology Plus drives for 16TB of raw capacity. It is powered by an AMD Ryzen V1500B processor running at 2.2 GHz and equipped with 32GB of DDR4 ECC memory. A 1.6TB Synology Enterprise Cache using two 800GB modules accelerates frequent read and write workloads. The unit is tested and validated before shipment.
This configuration fits organisations that need a pre-validated storage appliance for file services, backup targets or virtualization storage at the edge. The four 1GbE ports support Link Aggregation for throughput and failover without extra hardware. Buyers who require 10GbE or 25GbE connectivity out of the box should evaluate other models, as the included interfaces are 1GbE only. The single PCIe Gen3 slot allows a network upgrade later if the budget or switch infrastructure is not ready today.
The processor supports a maximum of 32GB of DDR4 ECC memory and this unit already reaches that limit. No further RAM expansion is possible, so workloads that demand more memory for large deduplication tables or heavy virtualization must run within this constraint. The installed 32GB matches the platform maximum exactly.

The two 800GB Synology Enterprise Cache modules are rated for heavy write workloads; their endurance depends on daily write volume, and Synology DSM reports remaining life so you can plan replacement before wear-out.
Sequential reads above 2,000 MB/s and writes above 1,300 MB/s in Synology tests exceed the combined 1GbE bandwidth, so the network ports become the first bottleneck under continuous load.
The 1U chassis operates within 0°C–35°C ambient; four drive bays and the Ryzen V1500B generate measurable heat, so internal fans run continuously at controlled speeds to keep components within thermal limits.
