Without ZFS you would require a reliable hardware RAID controller (if

And we always use geom_mirror with UFS ...
That would work but I don't recommend for new setups. ZFS offers you a
lot of operation which in my opinion alone is worth the overhead.
Without ZFS you would have to use either large raw image files in UFS or
fight with an old fashioned volume manager.
One thing to note - ZFS isn't holy grail and has own problems too. For
example there is not fsck_zfs and there are some cases where you can end
up with broken pool and because of its complexity the only thing you can
do is to restore from backup. This can occured on ZFS with higher
probability than on simple UFS2.
