A compact 1U rackmount NAS with four drive bays, an AMD Ryzen V1500B processor, 8GB DDR4 RAM, 3.2TB cache and 16TB of pre-installed drives, fully assembled and tested
The Synology RS826+ is a 1U rackmount network-attached storage server powered by an AMD Ryzen V1500B four-core, eight-thread processor running at 2.2 GHz. It arrives fully assembled and tested with 8GB DDR4 ECC memory, 3.2TB of Synology Enterprise Cache on two 1.6TB modules, and four 4TB Synology Plus NAS drives for 16TB total capacity. Four drive bays accept 3.5-inch SATA hard drives or 2.5-inch SATA SSDs.
This unit suits teams that want a pre-configured, web-managed NAS with four 1GbE ports for link aggregation and a PCIe Gen3 slot for future 10GbE or 25GbE upgrades. It is not for buyers who require more than four drive bays, higher base memory than 8GB, or built-in networking faster than 1GbE without adding an expansion card. Operating temperature ranges from 0°C to 35°C.
The four drive bays and maximum 32GB DDR4 ECC memory define the storage and performance ceiling for this model. Two USB 3.2 Gen 1 ports provide direct-attached backup or peripheral connectivity. Dual 1.6TB cache drives accelerate frequent workloads, while the 100-240 VAC power supply supports global deployment.

Use standard Cat5e or Cat6 Ethernet cables for each of the four 1GbE RJ-45 ports to reach full 1000M speed.
Yes, a compatible 10GbE or 25GbE network adapter can be added to the PCIe Gen3 expansion slot while the four 1GbE ports remain active.
Run Synology's built-in storage benchmark tools or transfer large sequential files over the aggregated 1GbE links to confirm throughput.
