Compact 1U rackmount NAS with AMD Ryzen V1500B processor, 4GB DDR4, 3.2TB cache and 16TB of Synology Plus drives pre-installed
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 with four drive bays, 4GB of DDR4 ECC memory, 3.2TB of enterprise cache and 16TB of Synology Plus drives already installed. A 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor handles file services and applications.
Under Synology test conditions the unit delivers more than 2,000 MB/s sequential read and 1,300 MB/s sequential write, maintaining those rates across extended workloads rather than brief bursts. Four integrated 1GbE RJ-45 ports support Link Aggregation for load balancing and automatic failover. A PCIe Gen3 slot accepts compatible 10GbE or 25GbE adapters when network demand grows beyond the onboard interfaces.
This appliance replaces a dedicated file server or external DAS when an organisation needs centralized, web-managed storage with redundant networking in a shallow 1U form factor. The jump is worth it for teams that require ECC memory, hot-swappable SATA bays and the ability to add faster network cards without replacing the chassis. Buyers who need more than four drive bays or built-in 10GbE ports should consider larger rackmount models.

The unit operates between 0°C and 35°C ambient temperature, drawing power from a 100-240 VAC 50/60Hz supply within its 1U chassis.
No extra drives are required; the four 4TB Synology Plus NAS drives and two 1.6TB cache modules are already installed and configured.
Yes, each bay accepts compatible 3.5-inch SATA hard drives or 2.5-inch SATA SSDs, so older SATA drives can be added or swapped.
