  I wouldnt never do raid with only 2 disks, it doesnt seeem safe tbh, 3 disks min (2 disk as backup)

    Raid 5 with 3 drives survives one dying disk. Raid 1 (mirroring) with 2 disks survives one dying disk. if either setup loses two disks all the data is gone.

    When you run 3 disks then the odds of two failing are higher than if you run 2 disks.

    So 3 disks are not significantly safer and might even be worse.

    That being said: both setups are fine for home use, because you've set up real backups anyway, right?

    Raid 1 on two drives is perfectly reasonable.

      its little money vs time you spent on it (backups are almost always missing something)
