Hitachi make a new 7200rpm laptop HD

Come on apple, work out how to get one of these into the powerbooks, much better than their lethargic 4200rpm drives, it would certainly prompt me to buy one (er when the processors are also upgraded, oh and the graphics, etc..)

requires a better bus for it to make a difference. not to mention more noise and heat produced. and more cost.

I have no idea how power / it requires or heat it generates, the article doesn't mention. It is designed for portables though.

Saying that it'll require a new bus however isn't entirely correct. It may be that its increased transfer speeds will be lost, I'd have to look up the specs to see if this is true. However they claim that it has "20 per cent lower rotational latency, ie. the time it takes to get the data required in position under the read-write head". This will make a reasonably significant difference to the apparent speed of the drive compared to slower ones.
