Question

susan works in the research - and - development department. she recently purchased a large high - speed external drive and has attached the drive to her computer using a usb cable. her drive requires a minimum data transfer speed of 5 gbps and needs to have access to 600 ma/5 volts of usb power to function properly.
although the correct drivers are installed, when she plugs her drive into her workstation, the drive is not working. to troubleshoot the problem, she has connected her drive to a coworkers computer, where the drive functions properly. no additional cables are required for this drive.
which of the following is the most likely reason that susans external hard drive is not working?
susan has connected her drive to a usb 3.2 port, but the drive is only made to work with a 2.0 port.
susan has connected her drive using a type c cable, which does not have enough power for her drive.
susan has connected her drive to a usb 3.2 port, which does not support the minimum data transfer speed required.
susan has connected her drive to a usb 2.0 port, which does not have the required data transfer speed.

Explanation:

USB 2.0 has a maximum data - transfer rate of 480 Mbps (or 60 MBps), which is less than the 5 Gbps (5000 Mbps) required by Susan's drive. USB 3.2 ports support higher data - transfer speeds. Also, USB 2.0 may not provide sufficient power in some cases compared to USB 3.2. The most likely reason among the options given is related to data - transfer speed as the drive requires 5 Gbps and USB 2.0 can't meet that.

Answer:

Susan has connected her drive to a USB 2.0 port, which does not have the required data transfer speed.
