Compact 1U rackmount NAS for edge offices

The Synology RS826+ is a 1U rackmount NAS built for edge locations, remote offices, and growing business storage environments. It uses a 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor with 32GB DDR4 ECC memory. Four drive bays hold 3.5-inch SATA hard drives or 2.5-inch SATA SSDs. This unit arrives fully assembled and tested with four 20TB drives and 3.2TB enterprise cache.

Thermals rated to 35 °C with standard power input

The chassis operates from 0 °C to 35 °C and 5 % to 95 % relative humidity on 100-240 VAC 50/60 Hz power. Four 1GbE RJ-45 ports support Link Aggregation for load balancing and failover. Sequential read reaches 2,000 MB/s and write reaches 1,300 MB/s under Synology test conditions. A PCIe Gen3 slot allows 10GbE or 25GbE adapters to be added later.

Replaces standalone file servers needing

This configuration replaces a separate file server plus external cache tier by bundling 80TB raw capacity with 3.2TB enterprise cache in one 1U box. The jump is worth it when you need consolidated block and file storage with ECC memory and validated drives ready to rack. Buyers who need more than four drive bays or native 25GbE ports without an add-in card should evaluate larger models.

Questions about this item

How do I install the RS826+ into a rack and what step is often missed?

Use the included accessory pack to secure the 1U chassis in a standard rack, connect the AC power cord to the 100-240 VAC inlet, then attach network cables to the four RJ-45 ports; the step often missed is configuring Link Aggregation across the ports for failover and load balancing.

What maintenance will the four 20TB Synology Plus drives and two 1.6TB Enterprise Cache modules need later?

The drives and cache modules are sealed units with no user-serviceable parts; plan to replace any drive that SMART reports as degraded and replace cache modules if write endurance is exhausted, using only Synology-compatible replacements.

What limit appears first when the RS826+ runs sustained workloads at 35 °C ambient?

The 35 °C operating ceiling is reached first; beyond it the AMD Ryzen V1500B will throttle to protect itself, so keep intake air below that temperature and monitor system health via DSM.
