Data Management Glossary
A yottabyte is a unit of digital information storage capacity and it represents an extremely large amount of data. The prefix “yotta” denotes a factor of 10^24, which means that a yottabyte is equal to 1 septillion bytes or 1 trillion terabytes.
A yottabyte’s size in perspective:
- 1 yottabyte is equivalent to 1,000 zettabytes, which = 1 million exabytes (EB) = 1 billion petabytes (PB) = 1 trillion terabytes (TB).
- 1 yottabyte can hold approximately 250 trillion DVDs, each with a standard capacity of 4.7 gigabytes.
- It would take billions of years to transfer a yottabyte of data using a typical home internet connection.
The concept of yottabytes is often used when discussing data storage capacities on a global scale, such as the estimated amount of data generated and stored worldwide. However, it is worth noting that yottabyte-scale storage is currently not practically achievable using existing data storage technologies. The term is mainly used to conceptualize and illustrate the vastness of data that can be generated in the digital age, the majority of which by far is unstructured data.
