Tim,

Sure your system will use the space, but the performance will decrease if you store archive and redo logs on RAID 5. Also depending on your application, RAID 5 is not always the right thing to do.

We have multiple posts on our Oracle DBA forums addressing this issue. If you need more info check it out:

Hope that helps,
