will this hard-drive work in my 13in macbook pro?
I have a 13 inch macbook pro and I need more space, will this work?
no, this is a desktop harddrive which is too large to fit inside of a laptop. And in your case I would need to know a bit more info before recommending a drive to you. Do you know your model number and year? To get the model number you'll need to click the apple logo in the very top right of the screen and click about mac. If you have a newer one, and certainly if it's got a Retina display, you're unfortunately looking at a *very* expensive and unsupported upgrade as these units have proprietary SSD cards. Otherwise, and again it depends on model number, a standard 2.5" laptop HDD SSD or SSHD would work like a charm.
