If what you're after is sheer linear disk performance, then yes, RAID0 
with IDE would help (because a single ATA66 interface can conceivably 
drive 3 or 4 drives before saturating).

BUT: most of us do NOT need linear performance, we need "I/O's per second" 
(for things like mail servers, databases..) and in that case the 
non-interleaving nature of IDE will kill the cat.
