Alright, I was going to say something about how RAID 0 just stripes with no parody, a RAID 1 mirrors, so you get a whole drive of redundancy RAID 5 is stripe with parody so you need 3 drives minimum. If you loose a RAID 0 you lost half of your data, you can't recover from it, and chances are you lost all of the other side as well because your file system is totally hosed (though could someone please verify that). RAID 0 I have never seen to be useful. Sorry for the lack of good news. ~Ben On Thu, Mar 6, 2008 at 3:45 PM, Vince Kimball <[hidden email]> wrote: > I believe RAID 0 has no redundancy, so a single drive failure destroys > the volume. > > Scott R.
