Evolution of Data Storage Technology – Past and Present

Evolution of Data Storage Technology - Past and Present from how memory was stored and the costs involved over 30 years from 1980 to 2010

It is Sunday and at DW we sometimes publish some unique and interesting content which does fit the usual tutorials, news or ‘How to’ genre. So I thought I will share this interesting snapshot of 30 years of evolution of how data is stored. Ever wondered what data storage was like about 30 years ago? Recently I came across this great image which I am sharing below showing how data storage has changed so radically in the last 30 years.

  • On the left are Eight 2.5 GB IBM 3380 Disk Systems approx 20GB memory with an estimated value of over 1 Million USD and weighing about 2000 Kilograms. The data transfer rate in these systems was about 3 mega bytes per second.
  • On the right in present day, one MicroSD Card can store 32 GB memory alone with a value of just over $100 USD with a weight of 0.5 grams. The size of this card is about the size of the red button IBM Disk Systems would have to start it up. 😛

Do share through your comments on how fast technology has been evolving and your own experiences with the same.

Now that’s interesting :). And at the rate technology is evolving, these cards will soon be a thing of past. Btw, it would be good if you could provide “save as pdf” and “print” options with every post, so that readers can save these interesting articles on to their system.
