It depends on the model. If a SATA disc is installed now, then it works. This is the case for models up to mid-2012 WITHOUT Retina. It does not work for newer models because they use SSDs with a faster interface. On the website ifixit.com you can see all repair/replacement instructions for all MacBook Pro models available. They also list the replacement parts and what the SSD looks like.
