Question

if we measure our brain storage in GB, then what would be its capacity?

Answer 1

2.5petabytes or a million gigabytes

Answer 2

You might have only a few gigabytes of storage space, similar tothe space in an iPod or a USB flash drive. Yet neurons combine sothat each one helps with many memories at a time, exponentially increasing the brain's memory storage capacity to something closer to around 2.5 petabytes (or a million gigabytes).
