| A hard disk drive sometimes abbreviated as a hard drive, HD, or HDD is a non-volatile data storage device. It is usually installed internally in a computer, attached directly to the disk controller of the computer`s motherboard. It contains one or more platters, housed inside of an air-sealed casing. Data is written to the platters using a magnetic head, which moves rapidly over them as they spin. Internal hard disks reside in a drive bay, connected to the motherboard using an ATA, SCSI, or SATA cable. They are powered by a connection to the computer`s PSU |
