I’m still ZFS on Ubuntu. Unlike most people though I don’t use the parity distributing raid stuff, I just have three drives in a mirror. It is of course at the expense of throwing lots of drives at the problem, but my data size is small <3TB so it doesn’t really matter.

It means I can survive two drive failure and I don’t care about rebuild times and any single drive can be pulled from the machine and taken elsewhere with all my data on it.

I am thinking of moving to the same setup using FreeNAS instead.
