From rom

"even in a two-disk server, you can put the transaction log onto the
operating system disk and reap some benefits."

Context: I have a two disk server that is about to become dedicated to
postgresql (it's a sun v40z running gentoo linux).

What's "theoretically better"? 

1) OS and pg_xlog on one disk, rest of postgresql on the other? (if I
   understand the above correctly)
2) Everything striped Raid 0?
3) <some answer from someone smarter than me>
