iPod What's the diff between the Classic 80GB drive and the 5th Gen 80GB drive?

I heard the new ones are PATA... is that true for the old? Also, what are the seek times and RPM speeds?

I am sure someone else can fill in the details but the only difference I know of is that the old 80 was 2 platters and the new one is only 1.
