Compact 1U rackmount NAS for edge and remote offices

The Synology RS826+ is a 1U rackmount network-attached storage system built for edge locations, remote offices and growing business environments. It ships fully assembled and tested with an AMD Ryzen V1500B four-core, eight-thread processor running at 2.2 GHz and 16 GB of DDR4 ECC memory. Four drive bays hold the included 48 TB of Synology Plus drives (4 × 12 TB) plus 3.2 TB of Enterprise cache (2 × 1.6 TB). Four 1 GbE RJ-45 ports provide link aggregation for load balancing and failover.

Thermals, noise and power in normal operation

The unit operates between 0 °C and 35 °C with 5–95 % relative humidity and draws power from a 100–240 VAC 50/60 Hz supply. Its compact 44 mm × 480 mm × 492.6 mm chassis weighs 6.4 kg and fits a standard 1U rack space. Front-panel LEDs show power, drive and 10/100 LAN status at a glance. Management is handled through a web-based interface with DHCP client support.

Bundled drives, cache

Four 12 TB Synology Plus NAS drives and two 1.6 TB Enterprise cache modules are pre-installed, giving 48 TB of raw storage and 3.2 TB of high-speed cache without extra procurement. The 16 GB DDR4 ECC memory is already fitted and can be expanded to 32 GB if workloads demand it. A PCIe Gen3 slot remains free for adding a compatible 10 GbE or 25 GbE adapter when network throughput needs grow.

Questions about this item

How do I install the Synology RS826+ into a 1U rack and what step do people often miss?

Mount the 44 mm high unit using the included accessory pack, connect the AC power cord to 100-240 VAC, link the four 1GbE RJ-45 ports, then run the web-based setup; the step often missed is configuring Link Aggregation on the switch for load balancing and failover.

Which components in the RS826+ will need replacement first and when?

The four 12TB Synology Plus drives and two 1.6TB enterprise cache modules are the only moving or wear parts; drives typically last several years under 0-35 °C operation, while cache endurance depends on write volume.

What is the first performance limit the RS826+ hits during sustained heavy workloads?

The four 1GbE ports cap aggregate throughput at roughly 1000 MB/s, well below the 2000 MB/s sequential read and 1300 MB/s sequential write the Ryzen V1500B and 16GB DDR4 can deliver internally.
