Neuroscientists estimate the brain’s storage capacity at roughly 2.5 petabytes that’s about 2.5 million gigabytes. To put that in perspective, one petabyte can hold roughly 200,000 two-hour movies. A full day of TV (24 hours) compressed reasonably would take about 0.008 petabytes. So 2.5 petabytes could store over 300 years of nonstop television. Of course, we don’t actually record everything like a hard drive, but the raw capacity is staggering.
