    USB2 device performs faster if connected to USB3 port !!

    Hi there
    I've noticed that when I connect a USB2 external drive to a USB3 port it actually performs better than when even on a "Hi-Speed" USB2 port. -- transfer rate from USB2 to HDD is around 10 - 15 Mb/s faster than when on a USB2 port.

    I have two USB3 slots on my computer -- I have a Targus USB3 powered hub connected to one of the ports and connect the USB2 disk to the USB3 hub.

    If you have any legacy USB2 disks it's probably worth connecting to the USB3 port --seems in my case to work much better.

    Not sure if you mix USB2 and USB3 disks on the same hub though -- might try that later.

    also noted that my native USB2 ports copy faster than Windows 7 used to.
    Used to get 22MB/s, now getting 27MB/s.
    Same hardware. That can only be good

    its because usb 3 lets the usb 2 drive run at its max
    when in a usb 2 socket the drive never gets to the theoretical topspeed of usb 2
