You will get MUCH better performance by RAIDing them together. As long
as backup is taken care of, you'll theoretically, get 4 times the
performance by having them set up as RAID0. (Theoretically. In
practice, it'll be closer to 2x most likely. Also depending on if you
do software or hardware RAID.)
As for filesystems, I personally prefer ReiserFS, but that's just
personal preference. If you're comfortable with ext3, then by all
means use ext3.
