A technician needs to connect an external SSD that must support transfer speeds up to 10 Gbps. Which port should the technician use?
- AUSB 3.2 Gen 2 (Type-C)
- BUSB 2.0
- CPS/2
- DSerial (RS-232)
Show answer & explanationAnswer & explanation
Correct answer: A. USB 3.2 Gen 2 (Type-C)
USB 3.2 Gen 2 supports up to 10 Gbps transfer speeds and is commonly implemented over USB-C connectors, making it suitable for high-speed external SSDs. USB 2.0 tops out at 480 Mbps, while PS/2 and Serial are legacy low-speed ports.
Why the other options are wrong
- B. USB 2.0 maxes out at 480 Mbps, far too slow.
- C. PS/2 is a legacy port for keyboards/mice, not storage.
- D. Serial ports are very low speed and used for legacy devices.
USB 3.2 Gen 2
A USB standard capable of up to 10 Gbps data transfer, typically implemented via USB-C connectors.
- USB 2.0 = 480 Mbps
- USB 3.2 Gen 1 = 5 Gbps
- USB 3.2 Gen 2 = 10 Gbps
- Often uses USB-C connector shape
Memory trick: Higher the Gen number, faster the data train.
