Oracle does not mind about Raid 5 or Mirroring. In the last company, we used both Raid 5 (Clients stipulation for cost) and Mirroring (for disaster failure).

If you want the best of both worlds, I would suggest Mirroring (or Oracle Membering) for the Redo Logs, on there own disks assuming large throughput, and then if you cannot justify Mirroring on the Data files, then use Raid due to the resilience it offers, but watch out for the Raid 5 got-yas.

You should be able to find a reasonable White Paper within http://technet.oracle.com
