With the rise of USB technology, external hard disks became alternative portable (and more resistant than the delicate internal HDDs) to make backups of the system, run some functions and take what might need a computer to another. Advantages of external hard drives. By its great storage capacity and its portability, external hard drives have become a great ally of the users of portable computers.
