Human brain can store one petabyte data!
According to British daily The Telegraph, one petabyte is the same as 20 million four-drawer filing cabinets filled with text, 13.3 years of HD-TV recordings, 4.7 billion books or 670 million web pages.

Our brain memory capacity is ten times more than previously thought and it can store as much as one petabyte data, almost the entire world wide web, indicated a stunning discovery.
The researchers say the finding is a bombshell in the field of neuroscience.
Professor Terry Sejnowski, of the Salk Institute for Biological Studies, in California and other scientists studied the memory centre of the brain of rat’s hippocampus tissue by reconstructing it in 3D.
They found that the brain synapses – the place where a signal passes from one nerve cell to another changed dimensions and affected memory capacity, according to a press release posted on Salk Institute website.
“Our data suggests there are 10 times more discrete sizes of synapses than previously thought,” said Tom Bartol, one of the researchers.
“ In computer terms, 26 sizes of synapses correspond to about 4.7 “bits” of information. Previously, it was thought that the brain was capable of just one to two bits for short and long memory storage in the hippocampus” he said.
The study was published in eLife.
