The Big Bang of Big Data

According to the latest estimates, the amount of digital data created or replicated globally has increased more than thirty-fold in the last decade, from two zetabytes in 2010 to 64 zetabytes last year.

According to the latest estimates, the amount of digital data created or replicated globally has increased more than thirty-fold in the last decade, from two zetabytes in 2010 to 64 zetabytes last year. But this amount is nothing compared to what is expected in the coming years. The volume of data generated worldwide is expected to exceed 180 zetabytes by 2025, an average annual growth of almost 40 per cent over five years. The rise of the IoT (Internet of Things), the development of 5G and social networks are the main drivers of this "Big Bang" of data.


With data volumes growing rapidly, there is no doubt that data management is a challenge. In fact, experts warn that data creation and replication will grow faster than installed storage capacity. In 2020, global storage capacity (installed base) reached 6.7 zetabytes, and is expected to grow by an average of almost 20% per year over the period 2020-2025. Currently, only a small percentage of newly created data is being stored: less than 2% of new data generated over the past year has been saved and stored until 2021.
