Remember, the more disks you have the higher the odds that one will fail. If you don't design the RAID system correctly to match your needs, you will exponentially increase the odds of a disk failure resulting in catastrophic data loss. If you need speed more than reliability and you religiously make system backups a striped system may benefit you. But if you will loose $10,000/min because of down-time while you restore from a backup and replace the damaged hardware striping is definitely not a good idea unless you do it properly with redundancy and reliability included.
