Why each option
USB 2.0 has a maximum theoretical transfer speed of 480 Mbps (Hi-Speed), which was a significant improvement over USB 1.1's 12 Mbps.
100 Mbps is not a defined USB speed - it is the speed of Fast Ethernet (100BASE-TX) and is not associated with any USB version.
400 Mbps is the transfer speed of FireWire 400 (IEEE 1394a), a competing serial bus standard from Apple and Sony, not USB 2.0.
420 Mbps is not a defined speed for any USB specification or any other standard interface.
The USB 2.0 specification defines Hi-Speed mode at 480 Megabits per second (Mbps), equivalent to 60 MB/s under ideal conditions. This specification was released in April 2000 and remained the USB standard until USB 3.0 introduced SuperSpeed at 5 Gbps. Real-world throughput is lower due to protocol overhead and hardware limitations.
