Question

Who found out the human brain has a memory capacity which is the equivalent of more than four terabytes on a hard drive?

Answer 1

As a number, a “petabyte” means 1024terabytes or a million gigabytes, so the average adult human brain has the ability to store the equivalent of 2.5 million gigabytes digital memory.

Answer 2

The experts estimate that if we compare our brain to a computer we can store approximately from a couple of terabytes to approximately 2.5 petabytes (1 petabyte = 1000 terabytes). However, this comparison is limited by the fact that the way the human brain creates and stores memories is nothing like a computer.
