From Huddo's link:
"One somewhat unexpected discovery was that this speedy 7200 RPM hard drive was no louder (or hotter) than its slower counterpart - an impressive testament to the PS3's sound-dampening design. In other words, there's really no reason not to buy a speedier hard drive for your PS3."
and
"Where you'll really appreciate a faster hard drive is transferring or downloading full games and other media onto the hard drive. For the faster speed 7200rpm drive, you'll pay around $20 extra across the board. So if you're in the market for a PS3 HDD upgrade, it's worth considering 7200rpm if you plan to frequently transfer gigs upon gigs MP3s and videos."
