Because architecturally, the physical design of mechanical parts like platters, heads, actuators, and spindle motors remain pretty much the same as of now in the modern hard disk drives. You can see how storage technology evolved in 60 years. you can imagine, how much was the cost of the disk at that time, and how much was the speed, performance, scalability of the application at that time point of time. And how this non-functional thing evolved during years. Nowadays, you can move around the world by keeping TBs of data in your pocket.

Key Points of IBM First Disk

  • Developed in 1956 by IBM
  • Height: it was 66 inches, more than the 6 feet
  • Mechanical part: 50 platters of size each having 24 inches
  • Weight : around 1 ton
  • Storage capacity : 4MB
  • Power consumption : obviously you see very large machine which consumes huge power

You can imagine, if there is no revolution of storage devices, one thing is sure, this disk drive will not fit in your mobile phone, tablet, laptop, or desktop. Hence, there was no scope of development for electronic gadgets.
