I would like to buy a 240 - 256GB SSD drive for my 17in Early 2011 MBP. After reading the SSD buying guide on the Macbook Pro forums, it looks like there are specific drives that work best based on specific models, i.e. SATA 2,3,6 etc. I do not really care about maximizing performance as I expect they would all perform much better than my HDD and the performance differences would be more subtle. After initially settling on getting the Crucial M4 256 SATA III drive, reviews on sites like newegg mention incompatibility issues with the Early 2011 17in MBP. Any thoughts or guidance on SSD drives from 240GB to 256GB that are confirmed to work with the 17in MBP from Early 2011? Many thanks!
