I was wondering if anyone knew of a site that reviewed USB 3.0 OTG cables? The wire cutter didn't have an article on them, I don't think many devices use them. Samsung phones, or at least the S5 use them, but really they don't need to be made well for phones because they don't get up to usb 3.0 speeds anyway. I want or that can get good speeds on the Pyra. The blue usb port on the back isn't usb 3.0, that is the usb 2.0/sata port right? To get usb 3.0 speeds a OTG adapter will need to be used?
