So I was having an issue with a bad sector in my 500gb Hard Drive that came standard in my Late 2011 MacBook Pro. I wanted to also to increase my internal storage as I travel a lot and tired of caring around an External hard drive. I researched several Hard Drive replacements and by far the 1 TB SSD Hard Drive that iFixit offered was superior to the rest. I also like the idea of replacing my Optic Drive with the Old hard drive as I hardly ever use my optic drive anymore.
The install went perfect. It took me pretty much 1 hour to take out the old hard drive and Optic drive, and install the new Hard drive and Old Hard drive into the optic drive adapter. Very Simple to do with the instructions provided... now it took another 5 hours to re-install the software but the hardware was a snap.
1. Backup using TimeMachine JUST before you shut your computer Off to Upgrade
2. Must have an 8gb or greater USB Drive to load OS onto so you can install on your new Hard Drive.
3. PRINT out the instructions for installing the Hardware and steps for re-installing the software.
