Which of the following statements about external hard drives is correct?

The correct statement highlights that most external hard drives connect to a computer using USB or eSATA. This is accurate because these connection types are widely adopted due to their ability to provide high-speed data transfer and ease of use. USB, in particular, is a universal standard that allows for plug-and-play functionality, making it convenient for users to connect external drives to various devices without requiring specialized connections or drivers.

Using USB ports, external hard drives can be easily connected to laptops, desktops, and even some gaming consoles, while eSATA can provide more direct access to the drive as if it were an internal drive, potentially leading to higher speeds than traditional USB connections. The prevalence of these interfaces is a key reason external drives have become a popular choice for additional storage.

While some external hard drives may require their own power supply, many modern ones are designed to receive power directly through the USB connection, making this statement about power requirements not universally true. Performance comparisons show that while external drives might be slower than some high-performance internal SSDs, many external hard drives, especially those utilizing USB 3.0 or faster, can be quite competitive in terms of speed. Finally, external drives are frequently utilized for backup purposes, which ensures that data can be stored
