![]() ![]() In 2013, USB-IF announced that it was taking USB up to 10 Gbps and, in doing so, changed the version number for all USB 3.x products. Many peripherals don't even need to go beyond USB 2.0. In fact, even today, the vast majority of USB ports and products don't go beyond 5 Gbps nor do you need them to. In 2008, the USB 3.0 standard launched, bringing USB up to 5 Gbps, a huge leap from the 480 Mbps speed of USB 2.0, and for many years that was as fast as USB could go. The different USB 3.x version numbers exist purely because the number has been iterated with each speed advancement. The spec sheets may not even list a generation number, though if they don't, you should assume that it's Gen 1 (5 Gbps). However, despite the USB-IF's desires, we still see most PC vendors listing their ports as USB 3.2 or USB 3.1, without necessarily telling you what to expect from them.
