(Also, if you use your 1Gbps port at full speed at the most peak time for bandwidth utilisation, for 37 hours in a month, and not at all outside of that, assuming 20 cents a megabit with 95th percentile billing, the costs you’ve incurred to your provider are $200. Also it doesn’t matter at all what you do after those 37 hours, the costs to the provider are the same. You doing 300TB in a month costs the same as you doing 16TB, if you do the 16TB the ‘wrong’ way.)
