The answer is - it depends on your requirements for redundancy. You can do both if you like. You could configure your "mirrors" via Oracle ASM and point them to two different arrays that can utilize any level RAID-0, RAID0+1 or RAID-5 redundancy - depending on how many spindles you want to use which translates to what ever your budget can handle.
Best Practice at most companies will vary depending on the criticality of the data being stored.
