There might be a better way to do it, but I've found it sufficient to
kick out some bad-from-the-factory drives. In one batch of 12 drives, I
found two that went ZFS offline due to data errors with just:
zfs create mypool/burnin
zfs set compress=off mypool/burnin
cat < /dev/zero > /mypool/burnin/zeroes
zpool scrub mypool
And then SMART knew about unrecoverable bad blocks. It's at least an
easy way to find the worst of them.
ZFS - because drives are crap.
