Compact 1U Rackmount NAS for Edge and Branch Offices

The Synology RS826RP+ is a 1U rackmount network-attached storage system built for edge deployments, branch offices, and remote business workloads. It arrives fully assembled and tested with four 12 TB Synology Plus drives for 48 TB of raw capacity. An AMD Ryzen V1500B processor with eight threads and 8 GB of DDR4 memory powers the unit. Dual 10GbE ports and four 1GbE ports provide flexible high-speed connectivity.

Upgrade from Slower Network or Standalone Servers

This system replaces slower 1GbE-only NAS appliances or standalone file servers that cannot saturate a 10GbE link. The jump is worth it when workloads demand sequential throughput above 1,300 MB/s write or 2,000 MB/s read, or when Link Aggregation across four 1GbE ports is needed for failover and load balancing. The included 2-port 10GbE adapter occupies the PCIe Gen3 slot, so no additional network card is required for 10GBASE-T connectivity.

Verify Rack Space, Power and Expansion Needs

Confirm the 1U form factor fits the allocated rack depth and that 100–240 VAC power is available at the mounting location. Operating temperature must stay between 0 °C and 35 °C with humidity up to 95 % RH. If future growth beyond four bays is expected, plan for a compatible RX426 expansion unit to reach eight bays. The PCIe slot is occupied by the included 10GbE adapter, so M.2 SSD caching or 25GbE upgrades would require a different configuration.

Questions about this item

What rack depth does the 44 mm high RS826RP+ need for mounting?

The unit is 44 mm high, 480 mm wide and 492.6 mm deep, so a standard 1U rack space with at least 500 mm usable depth will accommodate it.

Which slot accepts the included 2-port 10GbE adapter during installation?

Insert the adapter into the single PCIe Gen3 expansion slot; the common mistake is leaving the bracket screw loose, which can unseat the card under vibration.

When should the four 12 TB Synology Plus drives be replaced?

Plan replacement after the drives reach their rated workload limit or if SMART attributes show reallocated sectors; the hot-swap bays let you swap one 3.5-inch SATA drive at a time without downtime.
