If not for the shortage of Quantum drives that has forced them into a hideous RMA policy, I would recommend the Quantum drive. IBM would be a close second, with Maxtor a distant third. The Quantum does make a bit more noise, but if you're after performance, noise and heat should be secondary concerns. Ignore ATA100, it's useless for today's drives, and won't be useful anytime soon.
WD dropped the Expert line, it doesn't exist anymore.
