Hard Disk Drives (Ohga Shrugs)

Hard Disk Drives, also known as HDD are a type of data storage device.

History
HDD storage was invented in 1956 by IBM. Within the next ten years, it became the main form of secondary memory for computers. Over half a century after its invention, the HDD remains the chief method of secondary computer memory storage.

Early HDDs were sometimes the size of refrigerators and washing machines, storing mere megabytes of data. They were also very expensive, especially for smaller computers. Over the course of the 1980's, however, HDD storage went from being included in only a few computers to being included in all but the cheapest of PC's.

HDDs have constantly gained capacity and become less expensive at an exponential rate over the decades.
