Very very bigtime important feature, filesystem checksumming.  If you don't
think it's important, it's because you're not using it, and that means it
happens without your knowledge.  I've only seen two checksum mismatches in
the last 3 years on production servers, but without checksumming, it would
have passed undetected, and in the worst case it could be copied/replicated
into other things.  (Of course, in ZFS, it simply retried or re-read the
data from the other side of the mirror, silently corrected it, and my
monitoring system alerted me that the checksum mismatch counter had
increased.)

But ZFS is not the only thing that does filesystem checksumming...  BTRFS
comes to mind.  Not sure what else.
