...usb 2.0 speed was approx 4.25 min usb 3.0 speed was approx 1.95 min
That's about twice as fast. A 26MB/s data rate sounds about right for a USB 2.0 device, while 62MB/s appears low for USB 3.0. My own tests with WD Caviar Black 2TB drives, NEO USB 3.0 enclosure and HP USB 3.0 PCIe controller gave me readings of 142MB/s on freshly formatted drives.
