![]() ![]() What’s in a name? USB 3.2 specs and speeds Source: USB-IF Spec Name ![]() The USB Implementers Forum (USB-IF), the organization that develops and governs the USB standard, suggests that device makers use its “ SuperSpeed USB” designations (see table below) to simplify marketing to consumers, but manufacturers don’t always heed this advice. USB 3.1 Gen 1 is the same as USB 3.2 Gen 1, and USB Gen 3.1 Gen 2 is the same as USB 3.2 Gen 2x1. The most recent update is the USB 3.2 Gen 2x2 protocol, which uses two lanes of double-speed data traffic to top out at 20Gbps.Ĭonfusing matters more, the USB 3.2 single-lane protocols are basically renamed USB 3.1 protocols, which you may still see on some devices.Either way, the result is 10Gbps peak throughput. The next step up in speed bifurcates into two alternatives: the use of double speed lanes of data that abide by the old speed limit ( USB 3.2 Gen 1x2) or a single lane that operates at twice the speed ( USB 3.2 Gen 2x1). ![]() It allows a maximum throughput of 5Gbps to travel over a single lane of data and can use an old-school Type-A rectangular plug or the oblong USB-C connector.
