A compact 1U rackmount NAS with four bays, AMD Ryzen processor, 8GB DDR4 RAM, 3.2TB cache and 48TB of Synology Plus drives, fully assembled and tested
The Synology RS826+ is a 1U rackmount NAS built for edge sites and growing businesses. It ships fully assembled with an AMD Ryzen V1500B four-core processor, 8 GB DDR4 ECC memory, 3.2 TB of enterprise cache and four 12 TB Synology Plus drives for 48 TB raw capacity. Four 1 GbE ports and a PCIe Gen3 slot provide network flexibility.
Buyers who need more than four drive bays, 10 GbE or 25 GbE networking without adding a card, or memory beyond 32 GB should consider other platforms. The unit operates in 0 °C to 35 °C environments with 5 % to 95 % relative humidity and includes a 100-240 VAC power supply.
The 2.2 GHz AMD Ryzen V1500B delivers over 2,000 MB/s sequential read and 1,300 MB/s sequential write under Synology test conditions. Memory expands to 32 GB via DDR4 ECC slots and the PCIe Gen3 slot accepts compatible 10 GbE or 25 GbE adapters for future bandwidth growth.
Measured against everything we stock in Rack-Mounted NAS Servers, at today’s prices. Recalculated every night.

The unit arrives with 8GB DDR4 RAM, 3.2TB cache and four 12TB drives already installed, so no extra components are required for basic operation.
Yes, each RJ-45 port auto-negotiates down to 10/100 speeds, and Link Aggregation still provides load balancing and failover on older switches.
Open the web-based management console; the storage manager will list the 3.2TB cache pool and all four 12TB volumes with healthy status indicators.
