Universal Serial Bus(USB) was firstly introduced in the 90s. It was developed for connecting host devices(mostly PC) to peripheral devices(mobile, printer etc). By the time it got famous because of its ease of connectivity and low cost. We already had USB 2.0 and 3.0. But USB 3.1 is the newer version of USB. It was developed in 2013 but still, people get confused between USB 3.0 and USB 3.1. So lets find out the difference between USB 3.0 and USB 3.1.

Difference Between USB 3.0 and 3.1

Actually, the versions of USB like USB 2.0 or 3.0 or 3.1 are nothing but just show the speed of data transfer between devices. In USB 2.0, maximum data transfer speed was 480 MBPS. But since technology doesn’t stop at a point, so new types of devices are being invented, and they require higher data transfer speeds, the user needed more transfer speed for better performance. So later in 2008 USB 3.0 was introduced, which was capable of transferring data at 5GBPS speed, much better than that of USB 2.0.

After about half a decade, users started to feel lack of data transfer speed, so USB 3.1 was launched in 2013 which enables whopping 10GBPS data transfer speed that is just double to that of USB 3.0. Except for high data transfer speed, USB 3.1 is capable of supplying 100W power to devices which is enough to charge a large notebook or even a laptop.

Usually, USB 3.0 is also known as “USB 3.1 Gen 1” and USB 3.1 is known as “USB 3.1 Gen 2” as shown in the image below. But how can you check that your device got a USB 3.1 or USB 3.0 port? It’s so easy to specify a USB 3.1 port. USB 3.0 port has a simple sign of USB but a USB 3.1 port has the USB sign inside a battery or a USB sign with a power sign.

What is USB Type-C?

Every data cable has two ends having different USB ports. One port for the host which is rectangular shaped and most common port which is used to plug in hosts is USB Type-A. The other side of the cable is USB Type-B which is for larger peripherals. USB Type-A and USB Type-B has two different types, which are mini and micro USB and are used for smaller devices.

Every time you plug in your data cable in any of your devices, you have to flip it once or twice to find the right side but this problem is solved by USB Type-C which eliminates this flipping and makes connection easier and convenient. If USB Type-C standard is paired with USB 3.1, this pair can replace many other ports available in computers and even the charger port. But it’s going to take some time to make this change to all new computers.


USB types A, B and C determine just the shapes of USB but USB standards like 2.0, 3.0 and 3.1 represent the data transfer speeds. So you can not compare a USB type-C with USB 3.0 or USB 3.1 because it is a whole different thing. Whenever you see a USB Type-C, it’s not compulsory that it is a high-speed port. it can be USB 2.0 or 3.0 or even 3.1.
