Having been left with a very bad taste in my mouth earlier this year with all the SATA III/2011 MBP SSD issues, I had gone to greener pastures with a MBA. However, due to a recent deal I was able to score, I'm back in a 15" 2011 MBP (2.2 i7). Having read that a recent EFI update supposedly addressed the issues (and seeing positive results with the Samsung 830 series), I bought a 256GB model. I just got the MBP and SSD yesterday, and I'm disappointed to report that I'm having just as many issues (if not more) than I did earlier this year. I did a clean Lion install, and before doing anything else went through software update to make sure I got all the EFI and other updates. After doing that, I've had nothing but application crashes and kernel panics. It's to the point where I can barely boot it without having the dashboard client or something else crash. I can't even launch firefox (launch, crash...restart, crash, kernel panic, repeat as needed). Rebooting does not help. I did a verify/repair permissions on the SSD-nothing. Did both an SMC PRAM reset-nothing. Have not yet reinstalled Lion, but if it's anything like the troubles earlier this year that will not make a difference. The ONLY other thing not "stock" about the machine was the RAM-I put in an 8GB GSkill kit that I had on my old machine. I did see some threads that mentioned how RAM could cause some of these issues, but what I don't get is this RAM worked 100% flawlessly on my other 2011 MBP (with an Intel SSD). I've put the stock RAM back in to see what happens. Is there something else blatantly obvious I'm missing? Am I just destined not to run a SATA-III SSD in a MacBook Pro? I'm very frustrated and very disappointed, especially when I see so many "working flawlessly" threads around. I'd welcome any other suggestions for things to try or that I might have missed. Thanks.
