I am SO CLOSE to pulling the trigger on an SSD right now and I need one more help recommendations wise. I'm looking at mainly an Intel drive for my 2011 15" MBP. I know SF-based drives are faster but it seems like there are so much issues plagued with them and they are very costly as well. So I am only looking towards Intel drives for their reliability and price point. And so I have a few questions... Is the 320 issue free when it comes to the MBP? Can anyone weight in on the comparison between the 320 and the 510 or other drives? Provided that you own them and real world difference that is. And is TRIM necessary with this drive?
