The Progression of Data
I remember back in the late 90’s when 300MHz computers cost $3,000 and hard drives capped out at 500 MB. Image files were usually around 100-200 kilobytes and video files were read from DVD’s. Storing a 1080p movie title on the hard drive would have required 48 computers. Not to forget that downloading a 1GB file would have taken over 46 hours on a 56K modem downloading at 6kb/sec. Fast forward a couple of years and we saw the world transition from the megabyte to the gigabyte in storage capacity.
Last year, a company announced the world’s first terabyte hard drive –which is the equivalent of 1,000 gigabytes or 1 million megabytes. With the gradual progression in high quality media and software (FULL HD /4K videos, 15+ megapixel images, PC games) increasing demand for hard drives with higher capacity, it is only a matter of time we reach the next stage in data storage, the Petabyte…
… and then the Exabyte
… and finally the Zettabyte.
A Zettabyte (1,000 exabytes) is so enormous, every bit of data stored in computers on the planet amounts to only 2.5 zettabytes.
Here is an infographic that just shows just how large a zettabyte is.
