World Memory Statistics

World memory statistics refer to data about how much information humanity can store and process. This includes digital storage devices like hard drives and servers, as well as human memory capacity. For example, the total digital data generated globally reaches zettabytes (trillions of gigabytes). Human memory is estimated to hold around 2.5 petabytes of information. These statistics help us understand technological trends, data growth, and the limits of human cognition, guiding development in information technology, data management, and cognitive sciences.
