Let’s learn about the differences between USB 2.0 and 3.0


Most computers on the market today have a USB 3.0 port. But I’m right to say that most of the computers we use everyday have a USB 2.0 port.

What exactly is the difference between 2.0 and 3.0? The functionality of both ports is the same. But it depends on the data transfer speed. Also 3.0 port is a bit more expensive. Data transfer speed between two USB ports on the “signaling speeds” has been classified as USB 2.0 and 3.0. If it is a USB 3.0 port, you can see the blue inside.


Theoretically, the USB 2.0 standard allows us to see a maximum signaling speed of 480 megabits per second. The USB 3.0 Standard can achieve a maximum signaling speed of 5 Gigabits per second. From this signaling speed we can see that USB 3.0 is faster.

But in practical situations we will not be able to see this signaling speed. In everyday use USB 2.0 can expect a write speed of 7.9 MB / s to 9.5 MB / s and USB 3.0 11.4 MB / s to 286.2 MB / s Write Speed.

But all this speed depends on the drives you use. Also, in some USB Flash Memories, the speed may be limited by the manufacturer. For these reasons, you can not expect this speed from your port.
