However, this latest version also introduced a new SuperSpeed+ mode (20 Gbit/s) that comes into play when using a USB-C connector and the very latest models of devices.īecause USB 3.2 is still in development, it’s unlikely to be widely adopted until the industry has made its hardware fully compatible. Released in September 2017, USB 3.2 allows compatible devices to take advantage of the SuperSpeed (5 Gbit/s) or SuperSpeed+ (10 Gbit/s) transfer rates. The smartphones and other devices many people use today tend to feature USB 3.0 or earlier versions.

Yet despite being built into some of the latest hardware (newer MacBooks, for example), USB 3.1 wasn’t very widely adopted. Here the confusion arose, as USB’s creators called its new version USB 3.1 Gen 2 (second generation), while giving USB 3.0 the new name of USB 3.1 Gen 1 (first generation).

(Read more on the different types of USB connector here.) In 2013 came USB 3.1, which doubled speeds to 10 Gbit/s-known as SuperSpeed+-when using USB Type A and USB-C connectors. USB 3.1īy the time version 3.0 came along, USB was well established as the industry standard. Launched in 2008, USB 3.0 improved significantly on its predecessor USB 2.0 by introducing SuperSpeed, a new data transfer rate that increased processing speeds more than tenfold, from 480 Mbit/s to 5 Gbit/s. the lower the version, the slower the speed). USB 3.1 Gen 2 is backwards compatible with ports and connectors that use either:ĭata transfer speeds will vary depending on the version (i.e. All components in the chain-the two devices and the cable-must be USB 3.0 to achieve that later version’s high speeds. The same applies if you use a USB 2.0 cable with a USB 3.0 device.Ī USB 2.0 cable has four wires inside it-a USB 3.0 cable has eight-and so will only transfer data at USB 2.0 speed. So, if you plug a USB 3.0 flash drive into a USB 2.0 port, it would only run as quickly as the USB 2.0 port can transfer data and vice versa. You can plug a USB 2.0 device into a USB 3.0 port and it will always work, but it will only run at the speed of the USB 2.0 technology. Yes, USB 3.0 backwards is compatible-meaning it’s designed to work with older USB versions including USB 2.0 and USB 1.1.
