I've been meaning to upgrade my hard drive, for my Macbook Pro 13"(latest model) to a larger capacity (I have the original 320gb). Was doing some reading and found that you can also get faster speeds from certain hard drives. My main concern is however - battery life and noise/vibration. My main goal is more capacity so I don't want to sacrifice battery life or anything else for a bit more speed. I've been looking at these two here - http://www.newegg.com/Product/Product.aspx?Item=N82E16822136835 http://www.newegg.com/Product/Product.aspx?Item=N82E16822136546 I would get the scorpio black if it didn't decrease battery life (noticeably) or create more noise/ vibration. But there are many conflicting reviews out there as well as for varying laptops. And would these operate cooler/hotter or about the same temp ranges?
