What is the maximum data transfer rate of USB 3.0 (SuperSpeed)?
- 480 Mbps
- 20 Gbps
- 10 Gbps
- 5 Gbps ✓
Correct answer: 5 Gbps
Option D (5 Gbps) is correct because USB 3.0, branded SuperSpeed USB, has a maximum data transfer rate of 5 Gbps, which is approximately ten times faster than USB 2.0 Hi-Speed at 480 Mbps. Option A (480 Mbps) is wrong because 480 Mbps is the maximum speed of USB 2.0 Hi-Speed, not USB 3.0. Option B (20 Gbps) is wrong because 20 Gbps is the transfer rate of USB 3.2 Gen 2x2, a later specification that uses two lanes simultaneously. Option C (10 Gbps) is wrong because 10 Gbps corresponds to USB 3.1 Gen 2, also known as SuperSpeed USB 10Gbps, which is a faster variant introduced after USB 3.0.
