IMAGINE YOUR BODY AS A HARD DRIVE: YOU COULD STORE THE WHOLE WORLD'S DATA

By
If your body was a hard drive, how much data could it store?

Your DNA and your brain are the two primary storage entities in your body. Each has its own storage capacity, but combined they can do wonders!

A single gram of DNA can store around 215 petabytes of data (215 million gigabytes). To put it in simple terms, DNA could store all of the world's data in one room! If we extracted the entire DNA from your cells, we would end up with a mass of 250 grams. This means, your whole DNA can store around 53,750,000,000 Gigabytes of data.

On the other hand, your brain can store approximately 1 petabyte of data (1,000,000 gigabytes). Unlike DNA, the brain’s capacity to store information is more limited, that’s because old data must be erased to make space for new one. As for DNA, it can keep on expanding and replicating to store more and more information.

Combining the storage capacity of both your DNA and your brain, the total would be 53,751,000,000 Gigabytes. The most powerful supercomputer right now is the Chinese Sunway TaihuLight, which can store up to 20 petabytes of data (20,000,000 gigabytes). That’s only 0.04% of your body’s storage capacity! This means your body has a storage capacity that is equivalent to 2500 Sunway TaihuLight supercomputers.
