Questions regarding hard-drive upgrades for MBP 13 in.

I am using the WD Black Scorpio 500gb in my 13" Pro 2010 Macbook and its quiet. You can barely hear a slight hummmm from the laptop in that corner if it's quiet. Runs quick. It does use some more battery power. i basically get 7-8 hours vs 10. So nothing that would be a issue.

Thanks.

I think the battery life rating is basically if you leave the computer on, but not doing anything.

But other than that, it sounds like its exactly what I want.
