Admitting that the speed of USB depends on various factors. I did a simple test just to see what a typical speed of a USB 2.0 and USB 3.0 are

External Hard Drive (write speed):
USB 2.0: 27 – 29 MB/s
USB 3.0: 112 – 122 MB/s

Flash USB (write speed):
USB 2.0: 11.4 – 12.0 MB/s
USB 3.0: 12.0 – 12.8 MB/s

 

What are your typical speed for USB?
