Hey, I need your help I'm finally getting my brandnew 12" Powerbook soon, and I am planning to buy a new, faster HD for it. About a year ago, the Hitachi 7K60 was the way to go... it was the fastest, consumed less energy and didn't producte too much heat. Now, I can't find any good, new reviews of available 2,5" drives. Is 7200 upm still noticable better than 5400? Also, I'd like to have a quiet drive, and of course it shouldn't produce too much heat or eat my battery Any help/advise/link to good reviews would be appreciated... thanks!
