A 1U rackmount NAS with four drive bays, an AMD Ryzen V1500B processor, 4GB DDR4 ECC memory, four 1GbE ports, a dual-port 25GbE adapter and 24TB of Synology Plus drives pre-installed
The Synology RS826+ is a compact 1U rackmount network-attached storage server powered by a 2.2 GHz AMD Ryzen V1500B four-core processor with eight threads. It ships fully assembled with 4GB DDR4 ECC memory installed and four 6TB Synology Plus drives for 24TB total capacity. A Synology 2-Port 25GbE adapter is included in the PCIe Gen3 expansion slot.
Organisations that require immediate 25GbE SFP28 performance without sourcing and installing an adapter separately will benefit from this pre-configured bundle. Buyers who need more than four drive bays or a higher base memory configuration than 4GB should consider alternative platforms.
The array provides 24TB of raw storage across four 3.5-inch SATA drives, forming the primary capacity constraint for deployment planning. Expansion beyond the four internal bays is not supported on this chassis.

You need a switch or router with 25GbE SFP28 ports and compatible SFP28 transceivers or direct-attach cables to connect the installed adapter.
Yes, the four 1GbE ports operate independently and support Link Aggregation for load balancing or failover alongside the 25GbE link.
Run a large-file transfer over the 25GbE connection and confirm sustained throughput approaches 2,000 MB/s read and 1,300 MB/s write in DSM performance tools.
