Synology RS820RP+ 4-Bay RackStation NAS Diskless

The Synology RackStation RS820RP+ is a 4-bay rackmount network-attached storage device designed for businesses that need centralized, reliable data management in a compact 1U form factor. Powered by a quad-core 2.1GHz processor with AES-NI hardware encryption support, it handles file sharing, automated backups, surveillance, and lightweight virtualization. The 2GB of DDR4 memory is expandable to 18GB, allowing the unit to scale its multitasking capability as demands increase. Storage capacity starts at four bays and can be doubled to eight by adding a Synology RX418 expansion unit, providing a clear growth path without replacing the entire NAS.

The RS820RP+ earns its "RP+" designation through built-in redundant power supply support, a critical feature for environments where uptime is non-negotiable. A PCIe 3.0 expansion slot accepts either a 10GbE network card—unlocking sequential read speeds exceeding 1,621 MB/s—or an M2D18 M.2 SSD adapter for SSD caching to accelerate frequently accessed data. The advanced Btrfs file system underpins data integrity with support for up to 65,000 system-wide snapshots, enabling granular point-in-time recovery without consuming excessive storage. Running Synology's DiskStation Manager operating system, the RS820RP+ also provides access to a broad ecosystem of packages for everything from cloud synchronization and mail hosting to Docker containers and Active Directory integration.
