Say a popular creator uploads a 10 minute video. Once it’s uploaded a thousand users play the video simultaneously. Is the video copied to multiple drives? Or can servers stream a single file to multiple users?

On demand videos will be cached locally as well, meaning the file is stored in memory as well as on disk, making streaming to multiple requests even faster. As demand drops, other files will replace the video in the cache.
