Chapter 6, Problem 1TC

Explanation of Solution

Given:

An external hard drive for backups.

To find: The fastest connection used by the current external hard drives along with the speed.

Solution:

The fastest connection arrangement used by the external storage devices or external hard drives is Thunderbolt $3$.

The maximum speed of Thunderbolt $3$ for data transfer is $40$ Gbps (Gigabytes per second). It requires copper cables for successful connection establishment.

The Thunderbolt 3 connector uses the USB–C connection which enhances its compatibility for the external hard drives.

Thus, the fastest connection arrangement used by the external storage devices or external hard drive is Thunderbolt $3$ which has a maximum data transfer rate of $40$ Gbps.
