The History Of The Hard Drive @ ThinkComputers.org
 

In 1953, engineers in IBM’s California-based laboratory invented the very first hard drive. Since that first disk drive, technological advances have been made at an astonishing rate, with data capacity increasing and size and price decreasing exponentially, year on year. 60 years on, the hard drives of today are unrecognizable from the first models, which took up an entire room. Hard drives today are measured in terms of gigabytes and terabytes, rather than megabytes-an amount of data that would have been almost unimaginable in the early history of computers. Here we take a look back at the evolution of the hard drive as it grew from 5MB to 4TB.
