What I hate about FreeNAS is that it is not permissive of what kind of disks you put in. I bought a Drobo5N just because I was able to slap any drives I wanted,

What I hate about FreeNAS is that it is not permissive of what kind of disks you put in. I bought a Drobo5N just because I was able to slap any drives I wanted, in any size or configuration and it would just work. When FreeNAS can handle that, automatically and on the fly, I'll switch to that.
