Hard Drives ( hard disk )

A Hard Drive (sometimes called a hard disk) is a mass-storage device that is typically connected through your computer's IDE or serial interface SATA (Serial ATA) for internal drives, and through IEEE 1394, or USB for external drives (SCSI is an expensive option for either internal or external drives)
