Obviously you have been lucky to never be a victim of
silent disk corruption (or you just haven't noticed).
There are other people who didn't have that much luck,
ZFS' checksumming and self-healing is a blessing. If
you don't know how it works and call it marketing blah,
then I suggest you read up on it a bit.
And by the way, it doesn't take any significant amount
of CPU power on hardware that is not ancient. I agree
that ZFS is not suitable to run on ancient hardware.
It isn't designed for that.
You're free to use UFS, of course, and keep suffering
from its shortcomings.
