> 150 million DAU. Say 10% of these tweets contain pictures of average size 300kB each & 1% of tweets contain videos of about 100MB each.

My assumption would be that a new image is uploaded per 1000 tweets a day. As retweeting an image is more popular, that doesn't occupy space.

And 100 MB videos are pretty rare. Most are short, few seconds.
