    Don't try to save money buying USB2.0 for large 128 GB usb disk. USB3.0 is so fast so it's much easier use with less wait time.

    While not the full 128GB as advertised, 116GB to be exact after format, it will do the job I require. Great thumb drive to transfer large amounts of photographs btwn customers. Speed is quick thanks to USB 3.0! Only buy Ultra models or Ultra Plus!
