An attached drive, also known as an external drive, is a storage device that is connected to a computer or other electronic device through a physical connection such as a USB or Thunderbolt cable. This type of drive allows for additional storage space and can be easily disconnected and moved between devices. Attached drives are commonly used to store large files, backup important data, and expand the storage capacity of devices with limited internal storage. They come in various sizes and formats, including hard disk drives (HDD), solid-state drives (SSD), and flash drives. With the convenience and versatility they offer, attached drives have become an essential tool for managing and organizing digital files.
