To estimate how much storage data YouTube will need in the next year, we can look at historical data and make projections based on current trends. According to Google, YouTube users watch over a billion hours of video every day. In 2020, this translated to 37 petabytes of data every day. Assuming this rate of growth continues, we can estimate that YouTube will need approximately 13,505 petabytes (13.5 exabytes) of storage data for the next year. However, it's important to note that this is a rough estimate and there are many factors that could impact storage needs, such as changes in user behavior, improvements in video compression technology, and the introduction of new video formats. As a product manager, it would be important to regularly monitor storage usage and make adjustments as needed to ensure that YouTube can continue to provide a high-quality user experience.
