A 1U rackmount NAS with AMD Ryzen V1500B, 16GB DDR4, 1.6TB cache and four 12TB SATA drives pre-installed
The Synology RS826RP+ is a 1U rackmount network-attached storage server powered by an AMD Ryzen V1500B quad-core, eight-thread processor at 2.2 GHz. It arrives fully assembled and tested with 16 GB DDR4 RAM, 1.6 TB of Synology Enterprise cache on two 800 GB SSDs, and four 12 TB Synology Plus drives providing 48 TB of raw capacity. Four hot-swappable bays support 3.5-inch and 2.5-inch SATA drives.
This unit suits businesses that want a ready-to-deploy appliance with built-in caching and redundant power for continuous operation in space-constrained racks. It is not for buyers who need more than four internal drive bays without adding an expansion unit, or for workloads demanding 10 GbE or 25 GbE connectivity unless a compatible PCIe adapter is sourced separately.
Under Synology tested configuration the system delivers sequential read performance above 2,000 MB/s and write performance above 1,300 MB/s. Four 1 GbE ports support Link Aggregation to maintain bandwidth and provide automatic failover during prolonged transfers. The PCIe Gen3 slot allows adding faster networking or additional M.2 caching to keep latency low when heavy concurrent access continues over time.

A switch or router with four available Gigabit Ethernet ports and Cat5e or better cabling is required to connect all four RJ-45 ports for Link Aggregation or failover.
Yes, the four hot-swappable bays accept compatible 3.5-inch SATA hard drives and 2.5-inch SATA SSDs, so existing drives can be installed in any open bay.
In DSM Storage Manager, open the SSD Cache section; it will show the two 800GB cache drives as healthy and display read/write cache hit rates during workloads.
