Key characteristics of the USB 3.2 specification include: USB 3.2 identifies three transfer rates – 20Gbps, 10Gbps, and 5Gbps. The USB 3.2 specification absorbed all prior 3.x specifications. While USB hosts and devices were originally designed as single-lane solutions, USB Type-C ®cables were designed from the outset to support multi-lane operation to ensure a path for scalable performance. The USB 3.2 specification defines multi-lane operation for new USB 3.2 hosts and devices, allowing for up to two lanes of 10Gbps operation to realize a 20Gbps data transfer rate. It is a fast, bidirectional, low-cost, dynamically attachable interface that is consistent with the requirements of the PC platforms of today and tomorrow. USB continues to be the answer to connectivity and charging for PCs, Consumer Electronics, Display and Mobile architectures. The USB 3.2 Specification addresses this need by adding an even higher transfer rates to match these new usages and devices. In addition, user applications demand a higher performance connection between the PC and these increasingly sophisticated peripherals.

They require significantly more bandwidth to maintain the interactive experience users have come to expect.

As technology innovation marches forward, new kinds of devices, media formats, and large inexpensive storage are converging.
