Four-bay 1U rackmount NAS with AMD Ryzen V1500B processor, 8GB DDR4 ECC memory, 800GB cache, and 80TB of Synology Plus drives, fully assembled and tested
The Synology RS826+ is a 1U rackmount NAS built for edge locations and growing business storage. It uses a 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor with 8GB DDR4 ECC memory installed. The unit includes four drive bays for 3.5-inch SATA hard drives or 2.5-inch SATA SSDs.
This NAS suits teams needing a pre-assembled, tested system with 80TB of Synology Plus drives and 800GB enterprise cache ready for immediate deployment. It is not for buyers who require 10GbE or 25GbE connectivity without adding a separate PCIe expansion card. It is not for environments outside the 0°C to 35°C operating range.
A single PCIe Gen3 slot allows compatible 10GbE or 25GbE adapters to be added when bandwidth demands exceed the four built-in 1GbE ports. This slot is the only path to higher network throughput on this platform. Verify adapter compatibility before purchase.

The unit ships with 8 GB DDR4 ECC RAM and 800 GB (2 × 400 GB) enterprise cache installed. The platform supports expansion up to 32 GB if workloads grow.
Under Synology test conditions the RS826+ delivers over 2 000 MB/s sequential read and 1 300 MB/s sequential write, so large file transfers and backup jobs complete quickly.
Four 1 GbE RJ-45 ports support Link Aggregation for load balancing and failover. A PCIe Gen3 slot accepts compatible 10 GbE or 25 GbE adapters when higher throughput is needed.
