Waiting for my new rMBP and trying to decide what drive to get for a large volume harddrive for video editing, want to know whether I should go Thunderbolt or if USB 3.0 will be enough for video editing in FCPX. I know TB is quicker/better, but in a single drive setup (not raid) I'm not sure if I will notice any difference in speed between the two drives, assuming both are 7200rpm. USB 3.0 is a lot cheaper so if they are the same performance I'm fine to go with that. Also not sure if the issue of USB being 'burst packets' is still an issue in usb3.0 and whether that alone makes it worth it to go with TB. Does anyone have any experience editing video with USB 3.0 drives on the new rMBP?
