Hard Drive Size and Battery Life Query???

[peter202]

Hello people, just wandering if someone can help me with this.
I know that hd speed is a factor but will a 100gb drive use more power than a 80gb?
thanks

I'm not aware of any difference between capacity and battery life - even if there is, it's so small as to be unnoticeable.

I have not noticed any change in battery life since installing my 160GB drive in my MBP.

HD capacity doesn't really make any difference. Speed makes a huge difference. I also have the 160gb in my PB and actually appreciated the increased battery life and lower temperatures compared to the 7200 80gb I had over the performance it offered. 5400 is as fast but its acceptable and is a good compromise of heat and battery life used and is still faster than a 4200 which my sister has in her ibook and it feels terribly slow.
