A compact 1U rackmount NAS with four drive bays holding 48 TB, an AMD Ryzen V1500B processor, 4 GB DDR4 ECC memory, four 1 GbE ports and a two-port 10 GbE adapter for high-speed business storage
The Synology RS826+ is a 4-bay rackmount NAS built for edge locations and growing business storage environments. It ships fully assembled with four 12 TB Synology Plus drives, 4 GB of DDR4 ECC memory, and a two-port 10GbE adapter installed. The AMD Ryzen V1500B four-core processor runs at 2.2 GHz and supports memory expansion up to 32 GB.
The bundle adds 48 TB of raw capacity and dual 10GBASE-T ports without extra setup. Four integrated 1 GbE ports support Link Aggregation for load balancing and failover. A PCIe Gen3 slot remains available for future 10GbE or 25GbE upgrades. Sequential read reaches 2,000 MB/s and write reaches 1,300 MB/s under Synology test conditions.
Buyers who want a tested, pre-populated 1U appliance with high-speed networking will find it convenient. Organisations requiring more than four drive bays, higher base memory, or 25GbE connectivity out of the box should evaluate larger chassis or different configurations.

The AMD Ryzen V1500B supports DDR4 ECC expansion up to 32 GB so you can add capacity later as workloads grow.
Under Synology test conditions the RS826+ reaches 2000 MB/s sequential read and 1300 MB/s sequential write, so the write ceiling is the first bottleneck.
Operating range is 0 °C to 35 °C with 5 % to 95 % relative humidity; the 1U chassis uses internal fans to keep drives within those limits during 24/7 operation.
