Synology RS826+ 4-Bay Rackmount NAS

The Synology RS826+ is a 1U rackmount NAS powered by a 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor. It arrives fully assembled with 16GB DDR4 ECC memory and four 12TB Synology Plus drives for 48TB total capacity. A Synology 2-Port 25GbE SFP28 adapter is installed in the PCIe Gen3 slot. Four 1GbE RJ-45 ports support Link Aggregation. This unit suits edge locations, remote offices and growing business storage environments.

Check drive compatibility and network infrastructure

Verify that your rack provides a 1U space measuring 44 mm in height and sufficient depth for the 492.6 mm chassis. The four drive bays accept 3.5-inch SATA hard drives or 2.5-inch SATA SSDs only. Ensure your switch or router has SFP28 ports for the 25GbE links and RJ-45 ports for the 1GbE connections. Confirm the operating environment stays within 0°C to 35°C and 5% to 95% relative humidity. A 100-240 VAC 50/60Hz power source is required.

Integration into a business storage build

The installed 25GbE adapter frees the PCIe Gen3 slot for future expansion if additional network speed or other add-in cards are needed later. Four 1GbE ports provide immediate failover and load balancing without extra hardware. Memory can be expanded up to 32GB using compatible DDR4 ECC modules. Two USB 3.2 Gen 1 ports allow direct attachment of external backup targets or UPS signalling. The web-based management and DHCP client simplify deployment in existing network topologies.

Questions about this item

Does the Synology RS826+ ship with the 48TB of drives and the 25GbE adapter already installed?

Yes, the unit arrives fully assembled with four 12TB Synology Plus drives, 16GB DDR4 ECC memory and a Synology 2-Port 25GbE SFP28 adapter pre-installed in the PCIe Gen3 slot.

The spec shows 16GB RAM now and expansion up to 32GB — which capacity should I choose?

The installed 16GB DDR4 ECC is sufficient for most small-business workloads; add another 16GB module only if you plan heavy virtualization or many concurrent Docker containers.

What do the quoted 2000 MB/s read and 1300 MB/s write figures mean for daily file transfers?

Those are sequential speeds measured under Synology test conditions; real-world SMB transfers over the four 1GbE ports or the 25GbE adapter will be lower and depend on drive mix, RAID type and client network.
