Faster Smaller 100GB Battery Eater or Slower Bigger 120GB Battery Conserver?

What you are asking is should I buy the Faster Smaller 100GB Battery Eater or Slower Bigger 120GB Battery Conserver? I just had a private exchange with MovieCutter about this and he says the 5400rpm 120 is what he ordered because you won't feel the difference and you will miss that extra 20GB of space. I concurr. You can so easily fill up 120GB - net 110 - in nothing flat. And remeber you will get longer battery life with the bigger slower drive too.krasi82 said:I was wondering if there is any noticable difference between the 5400 RPM HD and the 72-- RPM HD. Would you really notice the difference or wouldn't you at all. I was just wondering since I am thinking of buying one. thanx in advance.
