Storage Capacity of the Human Brain: 2.5 Petabytes


Stashed in: Science!, Best Videos, Singularity!, Storage!, Brain, Factoids, They did the math.

"The brain itself has a storage capacity of roughly 2.5 petabyes (a million gigabytes), or roughly 3 million hours of recorded TV."

It will be hard to fill my brain with 3 million hours of television.

Challenge accepted!

The brain is arguably the most complex structure in the known universe. It consists of an estimated125 trillion synapses, or the number of stars in 1,500 Milky Way galaxies. Unlike a hard drive that stores data on static, physical addresses, the brain embeds them in sophisticated paths between neurons. The remarkably resilient data storage technique allows us to remember our name, even if one pathway is destroyed or dies."

As humans we have not yet invented such a sophisticated data storage technique.

One day...
