The 3 drives as a Raid is probably set up to have on as a hot spare. A four drive Raid 1 is not really a Raid 1 it is either a Raid 01 or more likely a Raid 10. In a Raid 01 you stripe a pair of drives and then mirror the striped drives. The more common configuration is to create two mirror sets and then stripe them. This gives you fault tolerance with high though put.
