1080 What is the difference between USB 3.0, 3.1 and 3.2?Apr-02-22
USB 3 is the specification revision published by the USB Implementers Forum. Dot 0, dot 1, or dot 2 is the revision level of the specification. USB 3.2 superseded USB 3.1, which superceded USB 3.0. Each version of the specification retained what was in the previous specification and added something new. USB 3.1 added 10Gbps. USB 3.2 adds 20Gbps.

Our cards have not changed. We have updated the naming on our web site to conform with the latest specification.
