I have a 2011 15" MBP (2.3 GHz i7) with an Apple installed 256 GB SSD. My question is: is it worth it in terms of aggravation and risk to upgrade to a 6G OWC SSD? I already have an older model SSD that I can sell (it's a 240 GB OWC 3G SSD in the packaging) so the price differential is negligible. I have the bleeding edge MacBook Pro (it geek benches around 11000) and it's only "slowed" by the speed of a mediocre SSD. Would my performance significantly increase? Is it true that 2011 MacBook Pros don't officially support SATA3 devices? Thanks.
