2.0 vs 3.0 Is there a big difference between 2.0 – Q&A ...
The main difference between USB 2.0 and USB 3.0 is speed. USB 2.0 has a max speed of 480Mbps (Mega bits per second,) which converts to 60MBps (Mega Bytes per second.) Mbps vs MBps: MBps number will always be 8x smaller than the Mbps number. USB 3.0 has a much higher max speed of 5Gbps (Giga bits per second, ie 1024Mbps) which translates to 640MBps. 640MBps vs 60MBps, hence why USB 3.0 is advertised as 10x faster than USB 2.0.
