At present, there are 3 types of Universal USBs on the market. The first version, 1.0, is now rarely being used. USB 2.0 is the current standard technology. USB 3.0 is relatively new and is not used very often as yet. The differences between these types mostly pertain to the transmission speed, where the transmission of USB 3.0 is 10 times faster than USB 2.0. All USB sticks available at Usb Stick Producer function in standard 2.0 USB mode. On request, and for an additional fee, we can of course also supply the latest 3.0 USB version.
