USB 3.1 is a standard for connecting devices that offers faster data transfer speeds compared to its predecessor, USB 3.0. It can transfer data at rates up to 10 Gbps, which is double the speed of USB 3.0. This makes it ideal for transferring large files quickly, such as videos and high-resolution images. In addition to speed, USB 3.1 also supports more power delivery, allowing devices to charge faster. It uses a reversible connector, known as USB Type-C, which means you can plug it in either way. This versatility makes USB 3.1 a popular choice for modern electronics.
