![]() Whether you're looking for a fast data transfer speed for your flash drive or the ability to charge other devices, the right USB port is out there for you. Keep in mind that not all manufacturers use these indicators, so it's always best to check the documentation for your particular device if you're unsure which type of USB port it has. USB 2.0 ports are typically rectangular while USB 3.0 ports are often square-shaped or have a wider opening.Īlso, some USB ports will have an "SS" symbol next to them, which stands for " SuperSpeed." This is another indicator that the port is a USB 3.0 port or above. In these cases, you can also look for other indicators of the USB port type.įor example, you can often tell the difference between USB 2.0 and 3.0 ports by looking at the shape of the port. This is because certain manufacturers deviate from the conventions for USB port colors outlined above. Sometimes, color alone is not enough to determine the type of USB port. Other Ways to Determine the Type of USB Port As a result, you can generally use it to charge other devices, such as smartphones. This is because the yellow USB port indicates that it is always on, meaning it will continue to draw power even when the computer is turned off or in sleep mode. ![]() The yellow USB port is more commonly found on laptops while the red USB port is more commonly found on desktop computers. While the data transfer speed is the same as the red USB port, 20 Gbps, the two are not interchangeable. The yellow USB port is another color that can indicate either USB 3.2 or USB 3.1 Gen 2. For example, our USB-C memory sticks are often compatible with USB 3.2 ports. However, it is quickly becoming more common in everyday electronics as the demand for faster data transfer speeds increases. In the past, you would generally only find this type of USB port in high-end motherboards. This type of port can sometimes be orange instead of red. Its transfer speed can reach up to 20 Gbps, which has made it the fastest of all USB ports for many years. However, it can also be used to indicate a USB 3.1 Gen 2 port. The red USB port is generally classified as USB 3.2, which was released in 2017. Additionally, it supports duplex communication, meaning data can be transferred in both directions simultaneously. It is backward-compatible and can be used with devices that only support USB 3.0, 2.0, or 1.X. This is the easiest way to differentiate USB 3.0 vs 3.1 ports. The color is similar to USB 3.0, but it will appear as slightly more green-toned than the classic blue of 3.0. Released in 2013, it supports up to 10 Gbps data transfer speed, which is twice as fast as USB 3.0. The teal USB port is also known as the USB 3.1 Gen 1 or SuperSpeed+ (SS+) USB. Learn more in our guide to USB-A vs USB-C connectors. This type of USB port supports our USB-A connectors, which is the connector type that most people associate with USB connectors. However, the data transfer speed will be limited to the capabilities of those devices. The blue USB port is also backward-compatible, meaning it can be used with devices that only support USB 2.0 or 1.X. In addition, it can transfer data in both directions simultaneously. It was introduced in 2008 and offers a data transfer speed of up to 5 Gbps, which is more than 10 times faster than USB 2.0. The blue USB port is also known as USB 3.0 or SuperSpeed (SS) USB. It can be used with a range of devices, including keyboards, mice, microphones, speakers, digital cameras, CD-RWs, external HDDs, DVDs, and flash drives. The black USB port offers all of the features of the white USB port but with greater reliability. ![]() However, it can still only transfer data in one direction. It is significantly faster than the white USB port, with a data transfer speed of up to 480 Mbps. Due to the bandwidth needs of modern devices, this type of USB port is usually only found in older computers.Īlso known as USB 2.0, the black USB port was introduced in 2000. Additionally, the data can only be transferred in one direction. Its transfer speed starts at 1.5 Mbps and can reach 12 Mbps at full bandwidth. Introduced in 1996, it is the oldest USB port type and was originally developed for keyboards, mice, and other low-speed devices. The white USB port is also known as USB 1.X. But did you know that each color represents a different type of connection? Here's a quick guide from the USB Memory Direct team to help you make sense of it all. ![]() When you're looking at a row of USB ports, they all look pretty much the same. ![]()
