Hello, I have an early 2011 15" MBP, 2.2 i7, with the stock 500 GB Hitachi hard drive. I identified an SSD that I want to use to upgrade, especially given the size (500GB) and price ~$275: http://www.amazon.com/Samsung-Elect...D500BW/dp/B009NHAF3I/ref=cm_cr_pr_product_top First off, I was wondering if anyone here had experience with the Samsung SSDs. I looked at some of the threads here as well as upgrade instructions for an MBP of the same exact specifications on another website for an OWC SSD: http://www.bjorn3d.com/2011/11/a-complete-ssd-upgrade-kit-for-macbook-pro-early-2011/#.UJbM1ml25vZ http://forums.macrumors.com/showthread.php?t=1104245 http://forums.macrumors.com/showthread.php?t=1102430 My second question is, would this Samsung SSD be compatible with full 6G speeds if in the main bay? I don't know much about hard drives, but could someone explain to me the difference between SATA II/III and 3G/6G? My last question is if anyone knows where I can find a good video or the instructions necessary for upgrading my old HDD with the SSD. Thanks for the help.
