Compact 1U rackmount storage for edge offices

The Synology RS826+ is a 1U rackmount NAS powered by a 2.2 GHz AMD Ryzen V1500B four-core processor with 4GB DDR4 ECC memory installed. Four drive bays accept 3.5-inch SATA hard drives or 2.5-inch SATA SSDs for flexible business storage. Four integrated 1GbE RJ-45 ports support Link Aggregation for load balancing and failover.

Pre-installed cache and drives accelerate workloads

This unit ships fully assembled with 1.6TB of Synology Enterprise Cache provided by two 800GB modules plus four 6TB Synology Plus NAS drives totalling 24TB raw capacity. The cache tier speeds up random access for virtualisation and database workloads while the drives deliver large-volume sequential throughput. A PCIe Gen3 slot remains open for future 10GbE or 25GbE adapter upgrades.

1GbE and PCIe Gen3 define the I/O ceiling

Sequential read reaches 2000 MB/s and write 1300 MB/s under vendor test conditions using the four 1GbE ports in aggregate. Single-stream transfers cannot exceed the 1GbE line rate and the PCIe Gen3 expansion slot limits add-in adapters to x4 electrical lanes. Environments needing sustained multi-client throughput beyond 1GbE per client will require a network upgrade.

Questions about this item

Will the four 6 TB Synology Plus NAS drives need scheduled replacement?

The drives are rated for continuous operation in a 0 °C to 35 °C environment; replace any drive that SMART reports as degraded or after its rated workload limit is reached.

Which resource hits its ceiling first during heavy sustained workloads?

The installed 4 GB DDR4 ECC memory caps at 32 GB expansion, so memory bandwidth typically limits sustained throughput before the four 1 GbE ports or the PCIe Gen3 slot saturate.

How loud and hot does the 1U chassis get when running 24/7?

Operating temperature range is 0 °C to 35 °C with 5–95 % humidity; the unit draws 100–240 VAC at 50/60 Hz and uses internal fans sized for the 44 mm × 480 mm × 492.6 mm rackmount form factor.
