Although the transfer rate of external hard drives usually is slower than that of internal hard drives, external hard drives do offer many advantages over internal hard drives:
• Transport a large number of files.
• Back up important files or an entire internal hard drive (most external hard drive models include backup software).
• Easily store large audio and video files.
• Secure your data; for example, at the end of a work session, you can relocate or lock up an external hard drive, leaving no data in a computer.
• Add storage space to a mobile computer, such as a laptop or tablet.
• Add storage space to a desktop without having to open the case or connect to a network.
