Zettabyte Era in Data Storage
Introduction to the Zettabyte Era
The Zettabyte Era refers to the time period when global digital data storage and transmission surpass one zettabyte (ZB)—equivalent to one trillion gigabytes (GB). As data generation accelerates due to cloud computing, IoT, AI, and big data analytics, traditional storage and processing methods face significant challenges. This article explores the implications of the Zettabyte Era, the evolution of data storage technologies, and strategies for managing massive datasets.
Understanding the Scale of a Zettabyte
To grasp the enormity of a zettabyte, consider the following comparisons:
