USB 3.2 Arrives (With Much Confusion)

USB 3.2 Arrives (With Much Confusion)

If you’re confused by USB naming conventions, you’re not alone. We actually published an article back in 2015 explaining it. USB 1.0, 2.0, etc. refers to the specification while Type A, C, etc. refers to the plug. However, this somewhat intuitive method is about to get more complicated with the release of USB 3.2. The new USB standard has generations which include the previous versions of USB. So, USB 3.2 includes USB 3.1. Confused? Me too. Additionally, it’s commonly marketed as SuperSpeed USB. The bottom line is that USB 3.2 supports transfer speeds up to 20 Gbps where USB 3.0 only supported 5 Gbps. Here’s how the naming works:

Name Nickname Previous Name Transfer Speed
USB 3.2 Gen 1 SuperSpeed USB USB 3.0 5 Gbps
USB 3.2 Gen 2 SuperSpeed USB 10 USB 3.1 10 Gbps
USB 3.2 Gen 2×2 SuperSpeed USB 20 N/A 20 Gbps
