Unraid vs Freenas

Unraid vs Freenas

September 13, 2021 0 By Tobias

Unraid and Freenas are two Linux-based operating systems intended for home-built NAS and (home) servers, respectively. The biggest difference:

Freenas is free, Unraid has to be purchased once. Here we compare the two HomeServer / NAS operating systems in a table, followed by a conclusion.

Advantages found with Unraid and FreeNAS:

  • Easy to use
  • Interfaces
  • Virtual machine hosting
  • Hosting Docker/Containers

The advantages of FreeNAS:

  • Uses the mature and powerful OpenZFS
  • Standard RAID modes provide increased speed and fault tolerance
  • Fast performance without cache drives
  • Fault tolerance with only two drives

The advantages of Unraid:

  • Uses the maximum capacity of all data disks
  • Parity drives protect a large number of disks without reducing thereduce capacity
  • Easy file-level recovery
  • Data on working drives remains available during recovery
  • Saves power and extends drive life by shutting down unused drives

The disadvantages of FreeNAS

  • Fault tolerance severely limits capacity
  • No choice in file system

The disadvantages of Unraid

  • Mediocre performance without SSD caching

Unraid vs FreeNAS

Both FreeNAS and UnRAID are worthwhile solutions for creating your own file server. There is no clear answer to the question of which solution is better, and you will hear good arguments from proponents of both camps. FreeNAS is the better solution if you need Traditional Raid, while UnRAID is better if you are aiming for maximum capacity for non-critical data sets. We recommend SSD caching for both and your backup strategy will affect the equation.
