Amount of data created, consumed, and stored 2010-2023, with forecasts to 2028|数据存储数据集|数据增长数据集

The total amount of data created, captured, copied, and consumed globally is forecast to increase rapidly, reaching 149 zettabytes in 2024. Over the next five years up to 2028, global data creation is projected to grow to more than 394 zettabytes. In 2020, the amount of data created and replicated reached a new high. The growth was higher than previously expected, caused by the increased demand due to the COVID-19 pandemic, as more people worked and learned from home and used home entertainment options more often. Storage capacity also growingOnly a small percentage of this newly created data is kept though, as just two percent of the data produced and consumed in 2020 was saved and retained into 2021. In line with the strong growth of the data volume, the installed base of storage capacity is forecast to increase, growing at a compound annual growth rate of 19.2 percent over the forecast period from 2020 to 2025. In 2020, the installed base of storage capacity reached 6.7 zettabytes.

全球范围内，数据创建、捕捉、复制和消费的总量预计将迅速增长，到2024年将达到149泽字节。在未来五年，即至2028年，全球数据创建量预计将增长至超过394泽字节。2020年，数据创建和复制的数量达到了新的高峰。这一增长超过了之前的预期，原因是由于COVID-19大流行导致的增加需求，更多的人在家工作和学习，并更频繁地使用家庭娱乐选项。尽管如此，仅有一小部分新创建的数据被保留，因为2020年产生的和消费的数据中仅有2%被保存并保留至2021年。随着数据量的强劲增长，预计存储容量的安装基础也将增加，预计在2020年至2025年的预测期间，复合年增长率为19.2%。到2020年，存储容量的安装基础达到了6.7泽字节。
