HDD Hard Disk Drive

HDD is short for Hard Disk Drive, the English name for a hard disk drive. It is the most basic computer storage device. The commonly referred C: and D: drives in a computer are disk partitions belonging to the hard disk drive. Currently, common hard disk capacities include 80GB, 120GB, 160GB, 250GB, 320GB, 500GB, 640GB, and so on. Hard drives can be categorized by physical size into 3.5-inch, 2.5-inch, and 1.8-inch models; by rotational speed into 5400 RPM, 7200 RPM, and 10,000 RPM; and by interface type into PATA, SATA, and SCSI. PATA and SATA drives are typically used in desktop applications, offering large capacities at relatively low prices, making them suitable for home use. SCSI drives, on the other hand, are generally used in high-end applications such as servers and workstations, featuring smaller capacities, higher prices, but better performance and greater stability.
