2 notes on this. Isn't RAID0 just striping? It provides no data
redundancy, just balances the data between the 2. If you are looking for
redundancy wouldn't RAID 1 be better? Point 2: RAID is not a replacement
for periodic backups. A corrupted database will replicate through all
the RAID drives and you will have no way to recover your data in this
event.
