Ghosting a RAID Array is risky. Some people have done it with Norton Ghost 2001 so the latest one might work.
RAID0 = Stripping, fast read/write performance, no back up, 2 HDDs
RAID1 = Mirroring, fast read, slow write, data is always backed up, 2 HDDs
RAID0+1 = Sripping & Mirroring, Fast read/write, back up, 4 HDDs
RAID5 = Stripping with Back up, Fast read/write, if there is a failure on the Stripped array the third HDD can be used to replace either the 1st or 2nd drive, 3 HDDs
