RAID 0 has nothing to do with redundancy, but with performance. Look at RAID
1, it might be what you want. A number of newer controllers support creating
a RAID1 array from a single non-RAID disk. Same size, brand and model is
recommended but not required. Check your the documentation for your RAID
controller.

Raid 0 is striping, not mirroring. Exactly what do you want to
accomplish?



Redundancy so that every bit is saved to both drives so in case one drive
fails, the other is intact. How about self healing from the good drive?
