USB (Universal Serial Bus) is a data and power transmission system between computer equipment promoted by industry giants such as IBM, Microsoft, Intel, and Compaq.
Since its appearance, it has established itself as the predominant standard for communications between computers and peripherals.
However, the gradual improvement of its performance in terms of speed and energy transport has led to its widespread use in external storage units, hardware devices, charging accessories, among others.
USB 1.0 and USB 2.0 data transmission speed
Its first version, 1.0, barely reached a data transmission speed of 1.5 mb per second. This amount increased to 480 MB per second with the advent of USB 2.0.
However, the real quantum leap came with its latest version to date, ie USB 3.0.
USB 3.0 data transmission speed
USB 3.0 offers speeds of 4.8 gigabits per second, speeding up the exchange of information between compatible storage drives and devices: computers, phones, routers, TVs, printers, and more.
How to recognize the USB version of a flash drive
Therefore, it is important to know how to recognize if your USB flash drive or external hard drive is capable of exchanging information at high speeds.
Fortunately, there is a simple trick to identify the USB version of a device or computer port.
It consists of checking the color inside the connector. In USB 1.0 the color of the connector is white. In USB 2.0 the color of the connector is black. While USB 3.0 is distinguished from previous versions by its blue color.
