Have a look at OFA - Oracle Flexible Architecture - to get an idea of how an Oracle database should be optimally distributed across multiple spindles (disks).

Also, bear in mind that RAID theoretically has a performance cost - depends how good your controller is - really, any number of factors. However, in my experience, the situation rarely arises that the database is copied over to a non RAID system, so you can`t make comparisons. Most performance issues on an Oracle system can be traced to other issues than hardware......
