You have a customer who must perform a number of high-speed data transfers between her laptop and several different servers on a regular basis as part of her job. Traditionally, she has used USB 2.0, but she asks you if she should be using FireWire 800 instead. What do you tell her?

A. You tell her that USB 2.0 has a higher data transfer rate than FireWire 800 (IEEE 1394) and USB is more common on laptops than FireWire.

B. You tell her that FireWire 800 has a higher data transfer rate than USB 2.0 and FireWire connections are more common on laptops than USB 2.0 connections.

C. You tell her that parallel SCSI has higher data transfer rates than either USB 2.0 or FireWire 800 and this standard has been implemented on all new laptops.

D. You tell her that while FireWire 800 has higher data transfer rates than USB 2.0, FireWire ports are less common on laptops than USB 2.0 ports.

Solution

D. You tell her that while FireWire 800 has higher data transfer rates than USB 2.0, FireWire ports are less common on laptops than USB 2.0 ports.

Today, USB hard drives are more common and less expensive than FireWire or even FireWire/USB combo drives.

Comparing the FireWire 800 and USB 2.0 results on the MacBook Pro with the My Book Studio showed the FireWire 800 connection to be 35 percent faster at copying the file to the external drive, 51 percent faster duplicating that file on the external drive, and 37 percent faster copying over the 5000 files and folders.

FireWire 800 is faster than USB 2.0
