A 1U rackmount NAS with four bays holding 16 TB of storage, an AMD Ryzen V1500B processor and 16 GB DDR4 ECC memory, ready for business file services and backup
The Synology RS826+ is a 1U rackmount network-attached storage server powered by an AMD Ryzen V1500B four-core processor. It arrives fully assembled with 16GB of DDR4 ECC memory and four 4TB Synology Plus drives for 16TB of raw capacity. Four integrated 1GbE RJ-45 ports support Link Aggregation for load balancing and failover. A PCIe Gen3 slot allows future 10GbE or 25GbE adapter upgrades.
This unit suits teams needing a compact, pre-tested rackmount NAS with redundant 1GbE connectivity and ECC memory for data integrity. Buyers who need more than four drive bays or who require M.2 slots for caching tiers should look elsewhere. The 16GB memory is expandable to 32GB, but the chassis does not support additional internal drive bays beyond the four provided.
The 2.2 GHz AMD Ryzen V1500B four-core, eight-thread CPU determines the throughput ceiling for file services and virtualization workloads. Synology quotes over 2,000 MB/s sequential read and 1,300 MB/s sequential write under its test conditions. This processor also governs the maximum supported memory of 32GB DDR4 ECC across two SODIMM slots.

Yes, the four RJ-45 ports negotiate at 10/100/1000 Mbps, so they will link to your 10/100 switch at the lower speed.
Run the built-in storage benchmark in DSM or transfer a large file set over the aggregated 1GbE links and compare throughput to the published figures.
The unit ships fully assembled and tested with four 4TB Synology Plus NAS drives and 16GB DDR4 ECC memory pre-installed.
