I am under the 3 year warranty so I imagine the only way to do this would be to have apple do it. Presently I have a 500GB RPM drive and I was thinking about upgrading to a 1000GB drive or a SSD drive. If I moved to a SSD drive would there be a fast difference in speed? Is it expensive? When I bought my MacBook SSD's were only at a max of 250GB but I see that many Macbook's come with a 500GB SSD drive these days. The thing that worries me the most is cost. If I upgrade the drive at the Apple store I imagine they need to take my computer and cannot do it while I wait correct? How much would a 1000GB drive be or a 1000GB SSD drive be? Thanks..
