About the USB 3.0 flash drives, on my computer the Monster 32GB flash drive ran at about 16 MB/sec when plugged into a USB3 port, and about 13 MB/sec when plugged into a USB2 port. Probably the speed of the HDD is the limiting factor. There might be other uses that show a greater speed difference. A cheap USB2 flash drive ran at about 6MB/sec. So the Monster flash drive was about double the speed of a cheap one in a USB2 port and about three times the speed in a USB3 port.
