So where does it all end? Will we eventually be able to pack the entire internet into a pinhead? Physics wonks tell us there is a maximum theoretical amount of data you can squeeze into a finite amount of matter, but it’s a lot. For the microSD card given above it works out to about 567 bits, which is about 6.2 trillion trillion trillion trillion trillion MB.
It turns out that the capacity of hard drives has been growing at an exponential rate over time:
So, if they keep growing at this rate when would that microSD card sized storage device max out? Well, if the biggest microSD you can get currently is 64GB then I make it 132 years. And what could that microSD card fit on it? Well, the entire data storage of Earth in 2013 is around 735 exabytes, and that would take up a smidge over 0.000000000000000000000000000000000000000001% of the space on this “perfect” microSD card.
So clearly things can get even smaller, and store even more. Watch this space.
