A technician must select a USB connection that can move large video files between an external SSD and a laptop as quickly as possible. Which USB version supports theoretical transfer rates of up to 5 Gigabits per second?
USB 1.1 (Full Speed)
USB 3.1 Gen 2 (SuperSpeed+)
USB 3.0 (SuperSpeed)
USB 2.0 (High-Speed)
USB 3.0, marketed as SuperSpeed USB, introduced a new full-duplex data lane that raised the signaling rate to 5 Gbit/s (about 500 MB/s raw). All earlier standards are slower (USB 2.0 peaks at 480 Mbit/s, USB 1.1 at 12 Mbit/s). USB 3.1 Gen 2 doubles the speed again to 10 Gbit/s, so it is faster than 5 Gbit/s but not the 5 Gbit/s standard in the question. Therefore USB 3.0 is the correct choice.
