My MacBook Pro needed a performance boost and it seemed like the best way to do it would be to switch to an SSD. However, I did not like the idea of sacrificing space. Since I hardly ever use my Superdrive I figured, 'Why not swap it out?' So I did.
The repair ultimately took much longer than expected. I first took my MacBook apart put my SSD in the drive bay then as I attempted to perform one of the last steps in the guide, connecting the drive bay to the MacBook, I realized iFixIt had sent me the wrong part. So, I put my MacBook back together and sent an email.
The next day they had the write part shipped my way via my initial shipping method (FedEx). While I was waiting I went ahead and installed Mac OS on the SSD using a drive enclosure. A couple days later I got the package and completed the install. However, I could not successfully boot of the SSD; only off the HDD. After doing some reading I realized it was because my SSD was 6Gb/s and I had to swap the SSD and HDD. So I took my MacBook apart AGAIN and swapped them. Now everything works great and I am very happy with the performance improvement.
1. Check the optical drive bay when you get it and make sure it has the port you need.
2. If you get a 6Gb/s SSD, put it in the main drive bay and put your HDD in the optical drive bay.
