It it possible to add a SSD to my Macbook Pro 13". I just want a 8gb or 16gb to have my OS on. Then my standard hd for apps and files. It means I can boot up alot quicker and think its recommended to keep your OS on a seperate drive or partition. I seen a video that shows you how to remove your superdrive and add a second hd, this I do NOT want to do....
