Restoring from TimeMachine (I chose a new install of OS X Lion and then a restore of my data).Attaching the mounting screws of the original hard-drive to the OWC.Removing the bottom cover and the factory installed Toshiba drive.Taking a backup of your current system via TimeMachine.Installation of the drive is as simple as : My MacBook Pro supports 6Gb/s SATA out of the box, and although the System Profiler does not show TRIM support, this is not an issue, as the OWC SSDs have TRIM support built-in. When it comes to SSD options, not many companies provide reasonable pricing like OWC, let alone a 5 year warranty on their products – pricing is steep at USD 1,000.00 but the results are overwhelming and worth it. The 30-day return promise from OWC made the choice of the Mercury EXTREME Pro 6G SSD 480 GB drive an easy choice. Even with the 7200RPM Toshiba drive fitted, IO operations felt sluggish (even more so after installing the OWC) and I wanted to see if a SSD would make a big difference.

While my MacBook Pro is still a 2011 model with 8GB of RAM, I always felt that it could be a bit faster. There are very compelling reasons to upgrade your current MacBook Pro.
