A compact 1U rackmount NAS with four drive bays, 32GB DDR4 RAM, a 2-port 10GbE adapter and 16TB of Synology Plus drives pre-installed, powered by a 2.2 GHz AMD Ryzen V1500B processor
The Synology RS826+ is a 1U rackmount network-attached storage server powered by a 2.2 GHz AMD Ryzen V1500B four-core, eight-thread processor. It arrives fully assembled with 32 GB DDR4 ECC memory, a Synology 2-port 10GBASE-T adapter, and four 4 TB Synology Plus drives for 16 TB raw capacity. Four drive bays accept 3.5-inch or 2.5-inch SATA media. Four onboard 1 GbE ports support link aggregation and failover.
Organisations that require fast multi-user file sharing, backup targets, or virtualisation storage at the edge will benefit from the 10 GbE throughput and ECC memory. The single PCIe Gen3 slot is occupied by the included 10 GbE card, so no further network expansion is possible. Buyers who need additional PCIe cards, more than four drive bays, or 25 GbE connectivity should consider larger platforms.
The installed 16 TB (4 x 4 TB) array handles departmental file shares, backups, and light virtualisation workloads. Sequential reads reach 2,000 MB/s and writes 1,300 MB/s under vendor test conditions. Memory is fixed at 32 GB, limiting concurrent virtual machines or heavy deduplication tasks. Drive bays are fully populated, so capacity growth requires replacing drives with larger SATA units.

The unit ships fully assembled with four 4 TB Synology Plus NAS drives already installed, so no additional drives are required to start using it.
Yes, the four 1GbE RJ-45 ports and the PCIe 10GbE adapter operate independently, allowing simultaneous connection to different network segments.
The Power LED shows the system is on, each drive bay has an HDD LED for activity and status, and the LAN LEDs indicate link and traffic on the 1GbE ports.
