Thought about asking this here instead of in the peripheral forum since this application would be for the 2012 MBP in both non-retina and retina since we got USB 3.0 in them. Was wondering what peoples thoughts on which USB 3.0 in 32GB or larger was the best (if there is a real difference between the read/write speed). the other thing that I recently found while browsing at the Frys store was that some of the larger capacity ones are pretty thick so if you were to use one of them, you would not be able to use the other USB port unless you used a dongle -which I then feel you lose the aspect of just having a single small device in your pocket and not you have this other item in your pocket as well. The one I did find there that seemed to not be as wide that would block the other port was the Patriot supersonnic XT in 32GB for $29.00. What are your thoughts on these and who is using which ones and how are they working out.
