It can, but then it is too expensive for the small performance advantage...

Oracle Express Server has some advices (the hints there fit to nearly every Oracle database):
http://otn.oracle.com/products/exp_server/pdf/OEStuning.pdf starting at page 29. Oh no, they are recommending HW-RAID :-)

The truth: I don't have documents here recommending software RAID. All documents about Oracle tuning say that you always should use hardware RAID, if you are able to afford it. Sorry.
