I'm a little out of the loop on hard drives these days, but I'd like to upgrade the drive in my PowerBook. Speed is the key requirement. 6 months ago the Hitachi 7k60 series where about the fastest laptop drives out there (and I think the only 7200 rpm laptop drives?). Are these still the fastest available drives? Is there something faster/cheaper on the immediate horizon? Any other thoughts on these drives?

Thanks,
-Mike
