Carl,

For small disk farms, less than 20 Physical disks, I have always use Duplexing. Not that RAID5 is not a great it's just that having duplexing will allow you to better plan the performance of your database. If however you have a situation where you have multiple disks and define more than 5 RAID5 sets than you can go with RAID5.

You can reach me at lgilbert_at_gects.ge.com if you require configuration schemes that I have put together during small to large scale Oracle Installs.
