Yeah definitely wanting the redundancy, most of what I will be storing will not be life changing if lost just a big inconvenience, and for the life changing stuff I plan on having it backed up to cloud storage.

That is a good point about stress testing them, if memory serves me well I believe one of the 12TB would disconnect a while back maybe 2 or so years ago when I was using windows and doing large backups. I think the consensus around seems to just mirror the 6TB and mirror the 12TB drives separate, it’s probably what I will end up doing since in the end I am tripling the amount of storage and really allowing me to lose two drives albeit two different drives before data loss. Feel I may be getting a bit greedy with what I have and should just be happy with what I am getting with that. Looking at getting an upgrade in about a year or two either way.

That’s definitely I have to look into, the nixos page on ZFS had a link to a ZFS cheat sheet of sorts that I have been trying to wrap my head around, thanks for pointing it out though.

Thank you for that will have to have a look into it since I am quite new and I am not completely sure how to go about things in a way to not regret it later down the line in half a year or so.
