Having read up on ZFS I am very impressed with the level of paranoia. Especially its distrust of what has become "industry standard" solutions to data storage reliability. E.g.: * ZFS can not fully protect the user's data when * using a hardware RAID controller, as it is not able * to perform the automatic self-healing unless it * controls the redundancy of the disks and data. * ZFS prefers direct, exclusive access to the disks, * with nothing in between that interferes. That's the level of paranoia that I want! I was always convinced the RAID controllers are only specified to screw me over. I make the folks with tinfoil hats look like wannabes.
