USB 3.2 Gen 1×2 takes advantage of dual-lane operation capability of a certified USB-C cable, providing two lanes of 5Gbps.

Note that passive cables are mostly 1m or shorter in length in order to maintain optimal signal quality transferring data in USB 3.2 Gen 2×1.

This mode – marketed under SuperSpeed USB 10Gbps – is also the fastest speed that Thunderbolt 3 supports natively. Providing a single lane of 10Gbps, it can work with either USB-C cables or legacy USB 3.0 Type-A cables. USB 3.2 Gen 2×1 is alternatively known as USB 3.1 Gen 2.

This speed mode requires the use of certified, full-featured USB-C cables.

USB 3.2 Gen 2×2 defines data transfer rate at 20Gbps over two lanes at 10Gbps each, hence the name SuperSpeed USB 20Gbps on its official namesake logo.

The latest USB specification brings us four speeds altogether and they are as follows: Now that the original USB 3.0 has received two major updates, we are now at USB 3.2. This is largely due to the fact that each new USB standard absorbs all previous 3.x specifications and at the same time gives them new monikers. Some manufacturers also restrict certain operating modes depending on the type of cable and/or charger that you use.Since the introduction of USB 3.0, making sense of USB marketing names has been a source of frustration for consumers. Just remember that USB-C doesn’t automatically specify any kind of performance level in and of itself. USB-C, USB 3.2 Aren’t Always Hooked Together Combine a non-standard vendor implementation with a non-standard cable manufacturer implementation, and what you get is a recipe for trouble (and dead hardware).

Some major companies, like Nintendo, have built their own non-standard USB-C implementations. Look for brands specifically marketed as compatible with your device, stick to well-known products, and honestly, I’d check online before buying a USB-C cable for anything you care about. It is in your best interest to always use the USB-C cable provided by the device manufacturer, and never to buy a replacement cable assuming that any old brand will do.
