Users upload 500 hours of video every minute. After transcoding, all the resolutions of one hour take about 1 GB in total. How much new storage is needed per day?

Answer

About 720 TB per day. In review, anything from 360 to 1,440 counts as right.

The worked estimate

A day has 1,440 minutes: 500 × 1,440 = 720,000 hours of video a day. × 1 GB = 720,000 GB = 720 TB a day, before replication. That is about 260 PB a year, which is why cheaper storage tiers for old videos matter.

Numbers: Numbers to know.
