USB 2.0
Back in year 2000 USB 2.0 innovation was discharged with most extreme information perusing velocity of 60 megabytes for each second (MBps) which is in principle looks awesome however sadly in all actuality it's approach to low from this standard. Typical USB 2.0 pen drives have most extreme perusing pace of 10MB/s and composing velocity of just 5MB/s which is clearly moderate. So that why we require something which is more effective and quick with the goal that it can coordinated today's quick world.
USB 3.0
Dissimilar to past adaptations USB 3.0 give reasonable Transfer Rate of 500MB/S(which implies 10GB information can be moved into only 20 seconds).
It underpins bi-directional information exchange which implies you can read and compose information at full sped at a time.(this highlight was not accessible some time recently)
The force burden has been expanded to 150 mA with least working voltage dropping to only 4 Volts.
