There are two reasons: 1) Redo log groups are never used simultaneously, so they can reside on the same disk. Log members should not be on the same disks for increased survivability. That gives us 2 groups with 4 members, each two members sharing the same device - 4 disks alltogether. 2) It's because I say so and I'm an 8i OCP.
