Four-bay 1U rackmount NAS with AMD Ryzen V1500B processor, 32GB DDR4 ECC memory, 1.6TB Synology Enterprise cache, and four 16TB Synology Plus drives pre-installed
The Synology RS826+ is a 1U rackmount NAS built for edge locations, remote offices and growing business storage environments. It runs on an AMD Ryzen V1500B four-core, eight-thread processor at 2.2 GHz with 32GB DDR4 ECC memory. The unit ships fully assembled and tested with 1.6TB enterprise cache and four 16TB Synology Plus drives for 64TB total capacity.
Four integrated 10/100/1000M RJ-45 ports support Link Aggregation for load balancing and automatic failover. A PCIe Gen3 slot allows compatible 10GbE or 25GbE adapters to be added as requirements grow. Two USB 3.2 Gen 1 ports provide additional connectivity. The 100-240 VAC power supply operates at 50/60Hz within 0°C to 35°C and 5-95% relative humidity.
This configuration replaces single-drive or non-redundant setups with a tested, cache-accelerated array that delivers over 2000 MB/s sequential read and 1300 MB/s sequential write under Synology test conditions. The jump is worth it when uptime, data integrity and scalable 1GbE throughput matter more than raw capacity alone. Builders needing more than four bays or native 10GbE should evaluate larger chassis.

Each port negotiates up to 1 Gbps. Link Aggregation can combine them for load balancing and failover, but a single connection still tops out at 1 Gbps.
The bays accept 3.5-inch SATA hard drives or 2.5-inch SATA SSDs. The unit ships with four 16 TB Synology Plus drives installed.
Remove the chassis cover, insert the card into the PCIe Gen3 slot, secure the bracket, then replace the cover. The step often missed is installing the correct driver in DSM before the adapter becomes usable.
