Question
A user is experiencing slow performance when copying files to an external USB drive. What is the most likely reason?
A. The CPU is overheating
B. The USB port is USB 2.0 instead of USB 3.0
C. The firewall is blocking file transfers
D. The monitor resolution is too high
E. The RAM is faulty
Answer
B. The USB port is USB 2.0 instead of USB 3.0
Explanation
USB 2.0 has significantly lower transfer speeds compared to USB 3.0.
The most likely cause of slow performance when copying files to an external USB drive is the use of a USB 2.0 port rather than a USB 3.0 port. USB 2.0 ports have a maximum data transfer rate of 480 Mbps, while USB 3.0 ports support up to 5,000 Mbps (5 Gbps), making file transfers up to ten times faster under optimal conditions. If either the computer or the external drive is connected via USB 2.0, the transfer speed will be limited to the slower standard, resulting in noticeably slower performance, especially with large files.
To maximize transfer speeds, ensure both the external drive and the computer are using USB 3.0 ports and cables. USB 3.0 ports are often marked with blue color or labeled "SS" (SuperSpeed). Using the correct port and cable is the most effective way to achieve faster file transfers and avoid bottlenecks caused by outdated USB technology.
