Because ZFS offers redundancy and LVM features (and much more) in a more
modern way, e.g. during a rebuild only used blocks need to be
resilvered, resulting in much greater speed. ZFS is intended to entirely
replace MD-RAID and LVM.

Only drawback of ZFS is that it needs bare metal disk access and must
not (or at least should not) be used with hardware RAID controllers.
This makes it difficult to use with older hardware, e.g. HP ProLiants
which only have HP SmartArray controllers as disk controllers. It is
possible to put some RAID controllers in HBA mode, though ZFS docs
advise against it.
