RAID 0+1 or 10 can both stripe across multiple drives. RAID 5 does not
provide the best tradeoff between performance and availability. I suggest
you read "optimizing storage for exchange server 2003", the latest version
dated 19 June, page 12 in the section titled "Best Practices Common to
Multiple Architectures" for the latest guidance.
