A compact 1U rackmount NAS with four drive bays, AMD Ryzen V1500B processor, 8GB DDR4 memory, 1.6TB cache and 16TB of Synology Plus drives, fully assembled and tested
The Synology RS826+ is a 1U rackmount NAS built for edge sites and remote offices. It runs on an AMD Ryzen V1500B processor with 8GB of DDR4 memory. Four drive bays hold 3.5-inch SATA hard drives or 2.5-inch SATA SSDs. This unit ships fully assembled with four 4TB drives and 1.6TB of enterprise cache.
Network connectivity relies on four 10/100/1000M RJ-45 ports that support Link Aggregation. Sequential read reaches 2000 MB/s and write reaches 1300 MB/s under vendor test conditions. A PCIe Gen3 slot allows a 10GbE or 25GbE adapter to be added later. Memory can expand to 32GB for heavier workloads.
The chassis measures 44 mm × 480 mm × 492.6 mm and weighs 6.4 kg, fitting a standard 1U rack space. Drives, cache and memory are already installed and tested, reducing on-site setup time. Operating limits are 0°C to 35°C and 5% to 95% humidity. Builders needing more than four bays or native 10GbE ports will need a different platform.

The unit ships with 8 GB DDR4 ECC installed and can be expanded up to 32 GB when workloads demand it.
Under Synology test conditions the RS826+ delivers over 2 000 MB/s sequential read and 1 300 MB/s sequential write, so large file copies finish quickly.
The four built-in 1 GbE ports support Link Aggregation for load balancing and failover, while the PCIe Gen3 slot accepts 10 GbE or 25 GbE adapters for higher throughput.
