The Crucial BX200 offers great speed and value for an SSD drive. If you want to be able to access many old states of your hard drive, we recommend getting a backup drive at least twice the size of the hard drive on your Mac. If you use Time Machine to backup your Mac, it will save multiple versions of your hard drive at various points in time. While you can use two hard drives, one in the hard drive bay and one in the optical bay, I wouldn't recommend it in your case.

I don't know anything about the hard drive you've selected but I do know that it will fit into your hard drive bay - the 750GB indicates the amount of storage. The Big Question: Is the Price Right for the Storage Space You Need? The more important performance gain is simply ditching your old and slow traditional hard disk drive found in earlier Apple MacBook Pros (pre-Retina) by moving to an SSD. In fact, you're more likely to gain more work 'performance' if you bring an apple to your desk so you don't have to leave your workspace just to grab a snack. I sometimes get caught up in the tech specs, thinking that a tiny performance advantage really matters: For most people, the small differences between Solid State Drive (SSD) models just isn't worth quibbling over.
