Compact 1U rackmount NAS for edge and remote offices

The Synology RS826+ is a 1U rackmount NAS built for edge locations, remote offices and growing business storage environments. A 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor drives the system with 8GB of DDR4 ECC memory installed. Four drive bays accept 3.5-inch SATA hard drives or 2.5-inch SATA SSDs, and this unit ships fully assembled with four 16TB Synology Plus drives plus 3.2TB of enterprise cache.

Thermals noise and power draw in normal use

The chassis operates between 0°C and 35°C with humidity from 5 to 95 percent relative humidity. Power input accepts 100-240 VAC at 50/60Hz from a single AC cord. Four integrated 1GbE RJ-45 ports support Link Aggregation for load balancing and automatic failover, while a PCIe Gen3 slot allows compatible 10GbE or 25GbE adapters to be added later.

What this replaces and when the upgrade is worth it

The RS826+ replaces older 1U NAS units that lack ECC memory, multi-gigabit expansion or the sequential read and write throughput measured at 2,000 MB/s and 1,300 MB/s. The jump is worth it when a site needs validated enterprise cache, pre-populated 64TB capacity and a tested, ready-to-rack appliance. Buyers who need more than four drive bays or native 10GbE ports without an add-in card should look elsewhere.

Questions about this item

How do I install the 1U chassis and which step is most often missed?

Slide the unit into a standard rack using the accessory pack, connect the AC power cord to the 100-240 VAC supply, link the four 1GbE RJ-45 ports, then run the web-based setup wizard; the step most often missed is creating the storage pool on the four 16 TB drives before writing data.

What maintenance or replacement will the 3.2 TB cache need later?

The 3.2 TB enterprise cache uses two 1.6 TB modules in the PCIe Gen3 slot; treat them as wear items and plan to replace both modules together when SMART health indicators approach the vendor endurance limit.

What limit appears first on the AMD Ryzen V1500B during sustained 2000 MB/s sequential reads?

The four 1GbE ports cap aggregate throughput at roughly 4 Gbps, so network bandwidth becomes the bottleneck before the 2.2 GHz four-core processor or the 8 GB DDR4 ECC memory reach saturation.
