Re: How would you layout the files?

SAME - stripe and mirror everything.

Redo and Data should be fine together. In fact, with only 4 spindles available for the db, I wouldn't have it any other way. RAID-10 the 4 drives and mount it up as a single volume. Pray for the best.

The problem that people create by separating redo, is they limit the number of spindles and thus reduce the IOPS that can be supported. While often one spindle is enough for space, it is rarely enough in terms of performance (IOPS).
