RAID0 has no redundancy so all of the media is required for the RAID
to be operable. RAID1 and RAID5 have sufficient redundancy to store
complete information without complete drives.

One implication of that is that if either drive fails, all information
is lost. Since two drives are involved, chance of failure is about
double that of a single drive.
