  1. Any body know if a raid card can do a automatic rebuild of a hot spare in a raid 0 (striping)! Thanks

    No, that is plain impossible. Even the term "hot spare" in RAID0 context is meaningless. RAID0 has no redundancy and in case of a drive failure there is nowhere to rebuild the data from. When a disk dries, the array is dead. Any "rebuilding" would be pointless.

    If you have a really advanced RAID controller that supports logical drives on top of physical arrays then yes, a hot spare drive can be assigned to a disk array (not a RAID array) and the controller will faithfully "rebuild" all the logical drives using the hot spare. You will still lose all the data that was on the RAID0 logical drive(s) though.

    you need the stripping + mirrors to do that; the 0-1 option
