What is the transfer rate of a standard USB 2.0 Device?

• 250 Mbit/s
• 480 Mbit/s
• 100 Mbit/s
• 1 Gbit/s 

EXPLANATION

The now-aging USB 2.0 standard can theoretically transfer data at a very high 480 megabits per second (mbps), or 60 megabytes per second (MBps). That’s impressive, but not as much as the newer USB 3.0, which can handle up to 5gbps (640MBps)—over ten times as fast as the 2.0 maximum.
