Assuming these are not SAN attached and you don't have a huge write
cache, eliminate any configuration that includes raid 5. It'll be very
slow for writes. Of the three, the first option is the best. The
striping should eliminate the bulk of any contention incurred from
having logs, archived logs, and datafiles all on the same filesystem.
