What is 78 zb?

78 zb is most likely referring to 78 zettabytes. A zettabyte is a unit of digital information storage equal to 1 billion terabytes.

To put this into perspective, it is estimated that in 2020 the world's total data storage capacity was only 44 zettabytes. Therefore, 78 zettabytes would represent a significant increase in the amount of data being stored globally.

It is also important to note that storing such a large amount of data would require advanced technology and infrastructure to support it. It is believed that advances in cloud computing and artificial intelligence will play a key role in managing and utilizing such vast amounts of data.
