Carrying Portable Data Storage






Carrying Portable Data Storage

The early 20MB and 40MB portable hard drives were six to eight inches in diameter, weighed at least five pounds, and had to be mounted inside the PC’s case for general protection. The latest development in disk storage are portable systems that range from pocket-sized 40GB hard drives to data storage devices that look more like key fobs than disk drives.

Many available newer and smaller storage devices include a biometric security device to unlock the storage unit for access, such as a fingerprint recognition unit.

These portable hard disk and compact flash devices connect to the PC through several connections, including USB (the most popular), FireWire (IEEE 1394), and serial. Portable hard disk devices usually use a connecting cable that can connect directly to a USB port or through a USB hub. Smaller, finger-sized flash storage devices usually plug directly into the USB port.
