Yeah there's a screwup here. The earlier calculation is 0.54 PB of data per five years, not per day, including a tripling of the cost to achieve 3-way replication.

The same mistake is made for video. But one paragraph later the author uses the per five years value as if it's per day.

The estimation for a video's average size seems nuts too

> 1% of tweets contain videos of about 100MB each

I can't imagine the average video on twitter is taking up 100MB of storage.

Do you have to multiply by 3 at all? I thought AWS/Azure already do that redundancy storage for you
