To summarize: if you're running ZFS, it can protect you from
lots of sources of data corruption. It can't protect you from
RAM errors without ECC, so you should opt for ECC if integrity
is your goal.
None of the other filesystems protect you against RAM errors
either, so this is not a special requirement of ZFS.
