To calculate the additional cost of storing videos uploaded to YouTube over the course of a year, let's start by establishing some key figures. YouTube reports that 500 hours of video are uploaded every minute. Assuming an average video quality that requires around 0.75GB of storage per hour, this results in approximately 540,000GB, or 540TB, each day. Google relies on its own data centers for storage, so their expenses are primarily tied to the upkeep of these facilities. Let's estimate that they can store 1TB of data for $0.015 per GB, which is lower than their public cloud storage rates due to economies of scale and more favorable supplier negotiations: The daily cost would be approximately 540TB * $0.015 = $8,100 On an annual basis, this amounts to roughly $8,100 * 365 = $2,956,500 Thus, the estimated additional cost of storing videos uploaded to YouTube over a year would be around $2.96 million. However, this is a rough estimate, and the actual costs could be considerably lower when taking into account factors such as data compression, deduplication, and more efficient storage techniques.
