RAID NOT 0.

I'm working on recovering data from a failed RAID 0 array just using
the direct disk copier dd and some Python scripting to de-interlace
the data (I'm hopeful, but the teacher who brought the drives in knows
not to expect miracles). There was only one failed sector on one of
the disks, and the whole array was borked.

RAID 0 (i.e. striping) provides no redundancy whatsoever, it's only
meant to make big, high-bandwidth disks.

RAID 1 (i.e. mirroring) and 5 makes it so any one disk can fail and
all your data is safe.

I dunno much more about RAID than that. ;-D
