About Unraid

Unraid is a storage-first operating system that lets you mix and match hard drives of any size into a single unified pool. It spins down idle drives to save power and provides parity protection without the usual RAID complexity. The web-based management interface handles everything from disk assignments to user permissions.

Beyond storage, Unraid includes a Docker engine and native KVM-based virtualization. You can run containers like Plex, Nextcloud, or Home Assistant, plus full virtual machines with GPU passthrough. The community app store adds one-click installs for hundreds of services. It runs on standard x86 hardware and supports both Intel and AMD CPUs.

Unraid uses a paid licensing model with three tiers (Basic, Plus, Pro) tied to the maximum number of attached storage devices. The license is tied to a USB boot drive, not the hardware, making it easy to move your system to new hardware. It is especially popular with home lab enthusiasts and small businesses that want a simple, flexible NAS and server in one box.
