An exabyte (EB) is a unit of digital storage that equals one quintillion (1,000,000,000,000,000,000) bytes, or 1,000 petabytes (PB). It represents an immense amount of data, commonly used to measure large-scale digital storage capacities, global internet traffic, and massive datasets in fields like cloud computing, artificial intelligence, and big data analytics.

To put an exabyte into perspective, it would take about 11 million 4K movies or over 200 million HD videos to fill just one exabyte of storage. With the rapid growth of data creation—fueled by streaming services, IoT devices, and cloud computing—exabyte-scale storage solutions are becoming increasingly necessary for tech giants, research institutions, and enterprise data centers.
