Hey all! I am thinking of upgrading my macbook pro 13'''s disk for a 7200rpm. From what I've heard, the overall speed of the computer increases a lot and I like the higher responsiveness that a disk with a higher rotation velocity gives you. My doubts are only related to battery life. Certainly, the 7200rpm disk will consume more energy but how much? Could you give me comments from your experience? Do you lose a noticeable ammount of battery life when upgrading to a 7200rpm disk? Thanks!
