Difference between USB 2.0 and USB 3.0
The most notable difference is speed. USB 3.0 can transfer data at up to 625MBps. However, you can find ten times less speed while using USB 2.0. But, the problem is that it depends on the data cable that you are using and the device where you are transferring your data. Another difference is related to power usage. USB 2.0 can consume up to 500 mA power when USB 3.0 can consume up to 900 mA power.
Identify USB 3.0 Port on Laptop
If you purchased a new laptop and you do not have much technical knowledge, how can you identify the USB 3.0 port on your device, so that you get better speeds when you copy or move data? To make use of USB 3.0, you should identify the USB 3.0 port on your laptop. Generally, most Windows laptops come with one USB 3.0 port and one or two USB 2.0 ports.
Check if your laptop has a USB 3.0 Port
The very first thing that you should confirm whether you have USB 3.0 port or not. For that, open Device Manager. You can either go to Control Panel and select the Device Manager option, or you can search for it via Taskbar Search Box. You can also open it via the WinX menu. In Device Manager, you will see Universal Serial BUS Controllers or USB controllers. Expand the menu. Here, you should get USB 3.0 mentioned in the list of USB related entries.
If you have found such a thing, read the following guide. Otherwise, there is no need to follow the following guide. If your device supports USB 3.0, you can identify the port this way:
1: Check the Logo
USB 3.0 is also used as SuperSpeed USB. Generally, laptop manufacturers use the SuperSpeed USB logo to differentiate the port. You can find the ss mark along with the USB logo, which looks something like the following image:
