External Hard Drives
External hard drives are portable data storage devices that offer additional space beyond a computer's internal memory. They are compact, lightweight, and easy to use, making them an ideal solution for backing up important files, transferring large amounts of data between computers, or expanding a system's overall storage capacity. External hard drives can be connected to a computer via USB, FireWire, or Thunderbolt cables and are available in various sizes, speeds, and interfaces to suit different needs and budgets. They often come with their own power supply, but some models can draw power directly from the computer's USB port. External hard drives are an essential accessory for any computer user who values data security and convenience.
