I have an early 2011, MacBook Pro, 2.2 GHz Intel core i7, 750 GB SATA (w/ 653 GB free). I use the MBP for some correspondence and tables, email of a residential, not business, type and some Internet browsing. I am the only user of the MBP. I've read a lot about SSD's and the speed differences, etc. I've researched Crucial's SSD's and the installation and cloning of information, etc. However, just before I pull the trigger, I always ask myself, "Do I want to replace 759GB capacity with 240 GB capacity?" So, I need some advice, suggestions, slap-up-side-the-head.... Any and all thoughts considered and appreciated.
