A table is used to explain USB 3.1 Gen 1 vs Gen 2 and also USB 3.2 Gen 1, USB 3.0, USB 3.2 Gen 2x2... Oh, just watch the video already, this is such a mess it's too hard to explain in the description. USB 4.0 will perhaps be introduced next year, so perhaps I will need to do another video at that time. I also briefly explain USB connectors as it relates to the discussion. USB types discussed include: USB 1.0, USB 1.1, USB 2.0, USB 3.0, USB 3.1 Gen 1, USB 3.1 Gen 2, USB 3.2 Gen 1, USB 3.2 Gen 2, USB 3.2 Gen 2x1, USB 3.2 Gen 1x2, USB 3.2 Gen 2x2. This is such a mess, watch the video and you will have a better idea what each means.
