First, because it makes the array hardware-independent, capable of being
moved to a completely different controller without any difficulties like
controller-specific metadata on the disks. This can be important when
there is a hardware failure and no easy access to an identical
Second, because it allows ZFS to deal directly with the disks. If the
disks are hidden under a hardware RAID system, it can keep ZFS from
seeing problems when they first begin.
