raid0 means striping: +-50% of the data on one disk, 50% on the other, so if 1 disk fails, or the raid breaks, you'll lose everything! raid1 is mirroring, which allows you to lose a disk and still retain all data
Note that "lose everything" is a relative term. For production purposes, losing one disk of a RAID-0 pair *does* mean you've effectively lost everything. For forensic purposes, it means (simplifying *enormously*) that you have all the even-numbered blocks, or all the odd-numbered blocks (depending which disk you lost). Effectively, you've just got handed half the capacity as slack space, and can try to extract information on that basis....
