The one home server OS EVERY homelab builder should look at
If you’re getting into homelabs, smart homes, or DIY servers, you’ve probably heard the name Unraid flying around. But what actually is Unraid, why do so many people swear by it, and is it worth using in 2025?
In this video I break down Unraid in plain English, covering everything from the Array, parity drives, cache pools, the Mover, shares, appdata, Docker, virtual machines, and even the infamous USB boot device. Whether you’re building your first home server or you’ve already got a stack of HDDs ready to throw into a box, this will give you a clear picture of how Unraid works and why it’s such a flexible option.
# We’ll talk about:
• How Unraid handles storage differently from RAID
• Why the Array and parity system make disk failures far less painful
• How cache pools, SSDs, and the Mover actually work
• The importance of the appdata share and how Docker uses it
• The USB boot drive (yes… that thing)
• File systems like XFS, BTRFS and ZFS
• Best practices that will save you from corrupt containers, full cache drives, and general chaos
• How I run Unraid in my own smart home, including Plex, Home Assistant, Frigate, Node-RED, Mosquitto and more
If you’re into servers, NAS builds, home automation, CCTV, Plex, containers, or tinkering with anything vaguely nerdy, this one will help you get a proper handle on Unraid. It’s one of the most powerful homelab operating systems around, and once you understand how it works, it becomes an insanely capable tool for smart homes, media servers, and self-hosting.
