A compact 1U rackmount NAS with a 2.2 GHz AMD Ryzen V1500B processor, 32GB DDR4 ECC memory, and four 4TB Synology Plus drives pre-installed for 16TB of ready-to-use storage
The Synology RS826+ is a 1U rackmount network-attached storage server built for edge locations, remote offices and growing business environments. It arrives fully assembled and tested with 32 GB of DDR4 ECC memory and 16 TB of raw capacity across four 4 TB Synology Plus drives. A 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor handles file services and lightweight virtualisation workloads.
This unit suits teams that need a compact, pre-populated NAS with four 1 GbE ports for link aggregation and a PCIe Gen3 slot for future 10 GbE or 25 GbE upgrades. Buyers who need more than four drive bays, native 10 GbE ports or a deeper rackmount chassis should consider other models.
The single specification that decides fit is the four-bay 1U form factor combined with 32 GB of installed DDR4 ECC memory. This combination fixes the maximum internal raw capacity at 16 TB with the included drives and determines whether the physical depth of 492.6 mm fits the target rack.

The unit ships with four 4TB Synology Plus drives filling every bay, giving 16TB raw capacity out of the box. If you need more space later, you would replace those drives with larger compatible 3.5-inch SATA models.
That figure comes from Synology's internal test conditions using Link Aggregation across the four 1GbE ports. Real-world throughput will be lower and depends on your network switch, cabling, RAID type and the mix of file sizes you transfer.
The slot accepts compatible 10GbE or 25GbE network adapters, letting you move beyond the four built-in 1GbE ports when your workload demands higher bandwidth.
