Well, it woudl be hard to boot into dos and pick the data off the hard drive, because the whole idea behind raid 0 is to write some of the data to one drive while writing the rest of the data to the other drive. In other words, if say you have a word document, half of it could be on drive a and half on drive b, so you woun't be able to retrieve that word document. If you want the advantage of striping with some fault tolerance behind it you would have to go with either raid 0+1 (striping with parity), or raid 1 (mirroring). With raid 0+1 you need at least 3 hard drives, raid 1 only needs two, but that offers no performance enhancements.
