5400rpm hdd vs. 7200rpm hdd in a laptop
I have a Dell 700m laptop. It has 1gb RAM, Pentium M 1.7Ghz processor, and a 60gb hdd (5400rpm). My average battery life is right at 5hrs. I am looking into replacing the hdd for a faster one (7200rpm). My question is, will getting a faster hdd greatly reduce battery life? Is it worth the performance gain? Thanks for your input.
