To the outside world, FreeNAS<\/a> (TrueNAS) and UnRAID<\/a> appear far more alike than different. In effect, they are. Both are operating systems that allow you to leverage your own hardware as a NAS (Network Attached Storage) box, i.e. a highly-focused file server for sharing data across the network.<\/p>\n

From there, while sharing features such as the ability to organize data, run VMs and Docker, FreeNAS and UnRAID part ways. The most obvious difference is that FreeNAS is free<\/em>\u00a0and UnRAID isn’t, though it’s not expensive as such things go, being $60 to $150.<\/p>\n

However, cost is a trifling issue compared to the difference in how they handle storage. FreeNAS uses the traditional RAID modes baked into its OpenZFS file system, while UnRAID uses a file-level distribution system that bears more of a resemblance to JBOD crossed with RAID 3\/4, than RAID 5 or such.<\/p>\n

The FreeNAS interface looks different, but offer the same essential abilities to configure and manage the storage, as well as associated services such as VMs and Docker.<\/p>\n

Storage Handling<\/h2>\n

As mentioned, but far the most salient difference between FreeNAS and UnRAID is how they handle fault tolerance.<\/p>\n

The basic RAID modes offered by FreeNAS and its OpenZFS file system are:<\/p>\n
