Which means, 50 cents per Mbps/per month. Usually a 1Mbps means about 190GB of transfer over the course of a month, I think. So 1000 * 190GB = 0.190 PB per month.
412PB thus means ~ 2200 Gbit/s . Under my pricing, I get a whole lot less than $33M / month.
So, does your calculation involve storing that same 412PB?
