Compact 1U rackmount NAS for edge and remote offices

The Synology RS826+ is a 1U rackmount network-attached storage server built around a 2.2 GHz AMD Ryzen V1500B four-core processor with 4 GB of DDR4 ECC memory. It ships fully assembled and tested with four 20 TB Synology Plus NAS drives installed, providing 80 TB of raw capacity across its four 3.5-inch SATA drive bays.

Suits teams needing high-speed uplinks

Four onboard 1 GbE RJ-45 ports support Link Aggregation for load balancing and failover, while a pre-installed dual-port 25 GbE SFP28 adapter delivers high-throughput connectivity for demanding workloads. A PCIe Gen3 slot remains available for future expansion. Buyers who require more than four drive bays or need 10 GbE RJ-45 ports should look at other platforms.

Dual-port 25 GbE SFP28 adapter included

The factory-fitted 25 GbE network card provides two SFP28 ports for low-latency, high-bandwidth links straight out of the box. This single specification determines whether the RS826+ matches a network infrastructure built around 25 GbE switching.

Questions about this item

Will the four 1GbE RJ-45 ports and the 25GbE SFP28 adapter work with my existing 1GbE switch?

The four 1GbE RJ-45 ports connect directly to any 1GbE switch; the 25GbE SFP28 ports require a switch with SFP28 slots and compatible transceivers or DAC cables.

How can I verify the AMD Ryzen V1500B processor and the 4GB DDR4 ECC memory are recognised after first boot?

Log into the DSM web interface, open Control Panel > Info Center, and confirm the CPU shows AMD Ryzen V1500B with 4 cores and 8 threads and that installed memory reads 4GB DDR4 ECC.

Which items ship inside the box and which components must be sourced separately?

The box contains the RS826+ main unit, an accessory pack, an AC power cord, the pre-installed 2-port 25GbE adapter, 4GB DDR4 RAM and four 20TB Synology Plus drives; rails, SFP28 transceivers and additional RAM modules are not included.
