Disk Drive or Hard Disk Drive

A disk drive is a randomly addressable and rewritable storage device. The term can be broadly interpreted to include optical drives and in earlier times, floppy drives. However, in popular usage, it has come to relate mainly to hard disk drives (HDDs).
Disk drives can either be housed internally within a computer or housed in a separate box that is external to the computer. They are found in PCs, servers, laptops and storage arrays, for example.
They work by rotating very rapidly around a head or heads, which read and write data.
They differ from solid state drives (SSDs), which have no moving parts and offer greater performance, but also cost more and generally offer less capacity.

History of hard disk drive
Hard disks were invented in the 1950s. They started as large disks up to 20 inches in diameter holding just a few megabytes. They were originally called "fixed disks" or "Winchesters" (a code name used for a popular IBM product). A hard disk drive consists of a motor, spindle, platters, read/write heads, actuator, frame, air filter, and electronics.
The first computer with a hard disk was IBM’s RAMAC, which was used during the 1960 Olympics to calculate sports results. A bit later, in 1962, removable disk packs were developed – a forerunner of the floppy disk. In 1964, the CRC algorithm was introduced. It provided greater security by checking and comparing data before and after it was written to the disk. In 1971, the first 8-inch diskettes came onto the market.

    Domain 1.0: Hardware Domain 1.1: Categorize storage devices and backup media  FDD: Floppy disk drive. Magnetic storage device that uses a read/write head to read, record and erase data onto a floppy disk. Data is stored in binary fashion (0s and 1s). Standard data capacity for floppy disks is 1.44 megabytes (MB), although capacities ranging from 360 kilobytes (KB) to 2.88 MB were available over the lifetime of the technology. Considered obsolete since the PC99 standards, although still available on legacy systems and some specialty machines. HDD: Hard disk drive. Basic unit of permanent storage for computers. Works on same principle as floppy drives, except much larger capacities (< 1 terabyte (TB) currently) and the disks are solid platters. Majority of hard drives use magnetic storage and mechanical spindles and armatures, which make hard drives a vulnerable point for failure. Common interface types for hard drives include SCSI, EIDE and the current standard, SATA. In external versions, USB and IEEE 1394 (known as FireWire on Apple systems) interfaces are also common. o Currently, more computers are being released with solid state drives or devices (SSD), which use non-volatile flash memory to store data, similar to USB flash drives. SSDs are much faster, are less prone to failure since they have no mechanical parts and last longer. However, they are far more expensive, and not presently available in the same capacities as traditional hard drives. Apple uses SSD devices in many of their newer…
