Hard drives in their now traditional format have been with us for quite some time, since 1956 actually, but it was not until much later that they began appearing in home computers. Since then we have seen a steady evolution of technology which has increased capacity and added speed or reliability – with the most recent evolution in the desktop market being Serial Attached SCSI’s appearance on enthusiast boards. It took a further 20 years after the invention of the hard drive for a possible replacement to appear, and that was an early version of a Solid State Drive.
