|Today marks the 50th anniversary of the hard drive. When first introduced on September 13, 1956, the hard drive stored only 5mb and occupied the space of two refridgerators. Today, you can carry gigabytes of data in your pocket.
The integrated RAMAC was about two refrigerators in width and not quite as tall, and it literally weighed a ton. Its 50 24-inch platters were in a stack inside the unit, in an assembly that spun at 1200 revolutions per minute. The unit used two magnetic recording heads. The RAMAC could hold 5MB--about the storage that today is needed for one 5-minute MP3 encoded at 128 kilobits per second.
