Unraid

Unraid gives you ultimate control over your home server or media lab by breaking the rules of traditional RAID. Instead of requiring identical hard drives, you can mix and match drives of different sizes, brands, and speeds to create a massive, protected storage pool. You can easily add new drives at any time to expand your capacity without rebuilding the entire array or losing data.

Beyond storage, you can transform your hardware into a multi-purpose powerhouse. Use the built-in Docker support to run hundreds of apps like Plex or Nextcloud, or set up virtual machines to run Windows and Linux simultaneously. It is designed for enthusiasts who want a professional-grade NAS and application server that remains simple to manage through a clean web interface.
