Compact 1U rackmount NAS for edge offices

The Synology RS826+ is a 1U rackmount network-attached storage server built for edge locations and remote offices. It ships fully assembled with four 4 TB Synology Plus drives for 16 TB total capacity and 4 GB of DDR4 ECC memory. A 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor handles file services and virtualization workloads.

Four 1GbE ports plus dual 25GbE SFP28

Four integrated RJ-45 ports operate at 10/100/1000 Mbps and support link aggregation for load balancing and failover. A pre-installed two-port 25GbE SFP28 adapter adds high-speed uplinks through the PCIe Gen3 slot. Two USB 3.2 Gen 1 ports provide direct-attached backup or peripheral connectivity.

16 TB raw capacity in four 3.5-inch bays

The chassis holds four 3.5-inch SATA hard drives or 2.5-inch SATA SSDs, delivering 16 TB raw storage out of the box. Memory expands to 32 GB DDR4 ECC for heavier workloads. Sequential throughput reaches 2,000 MB/s read and 1,300 MB/s write under Synology test conditions.

Questions about this item

Should I pick the 4-bay unit with 16 TB of Synology Plus drives or look for a different capacity?

The listing provides four 4 TB Synology Plus NAS drives pre-installed, giving 16 TB raw capacity in a 4-bay chassis that accepts 3.5-inch SATA hard drives or 2.5-inch SATA SSDs.

What does the 2,000 MB/s sequential read figure mean once the RS826+ is in my rack?

Under Synology test conditions the Ryzen V1500B processor and 4 GB DDR4 ECC memory deliver over 2,000 MB/s sequential read and 1,300 MB/s sequential write, so large file transfers and backup jobs run at multi-gigabyte speeds.

How do the 25 GbE SFP28 ports and the PCIe Gen3 slot cap real-world throughput?

Two 25 GbE SFP28 ports are included via the Synology adapter, and the PCIe Gen3 slot can host additional 10 GbE or 25 GbE cards, letting aggregate bandwidth scale beyond the four 1 GbE RJ-45 ports.
