Point of my question was that write speed to USB flash-drive was faster in case of USB 3.0 port than in case of USB 2.0 port while I would have expected the same write speed both in case of USB 2.0 and USB 3.0.

@martin Theoretical transfer rates are never reached... USB2 is 480Mbits/s, so you should be able to achieve write rates of 60MBytes/s, but I have never seen a USB2 external disk go faster than 20MBs, while as an internal disk you can achieve 60MBs. Given the low write speed of your key, the USB2 bus is less of a limiting factor and you see less difference than with a better device (20MBs and 90MBs on my USB hard disk)
