The then-new USB 3.0 significantly increased the speeds of data transfer. USB 2.0 was only capable of a theoretical maximum data transfer rate of 480 megabits per second, while USB 3.0 was capable of 5 gigabits per second, or over 10 times faster. ... The data transfer speed of USB 3.1 is incredible – 10Gbps.

USB 3.0 Type B plugs are larger than USB 2.0 (or earlier) Type-B plugs; therefore, USB 3.0 Type-B plugs cannot be inserted into USB 2.0 (or earlier) Type-B receptacles. Micro USB 3.0 (Micro-B) plug and receptacle are intended primarily for small portable devices such as smartphones, digital cameras and GPS devices.

USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps). USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios: ... Bus-powered USB devices that requires more power than what USB 2.0 can provide are not compatible with USB 2.0.

To meet different needs, there are different types of USB flash drives based on the ports, respectively USB 2.0 flash drive, USB 3.0 flash drive, USB 3.1 flash drive and 3.2 drive. The biggest difference among them is the price and speed. ... 3.0 flash drive can deal with data at the speed of 625 MB/sec.

If you see a blue USB port, it's USB 3.0. It may also be marked on the outside of the port with either “SS” or “3.0.” If you don't see any blue ports or markings but you're still not sure, click the Start menu and openControl Panel. Within Control Panel, open System and Maintenance then Device Manager.

1.0 which was the original standard of USB, and 2.0 which is the improved version for newer devices. To the end user, the difference between these two devices is purely in its speed. USB 1.0 devices can only achieve a maximum speed of 12Mbps while 2.0 devices can theoretically achieve up to 40 times that at 480Mbps.
