cost of storage i added a new section on cost of storage i hesitated to do this without discussing it first however i have often seen statements of encouragement for people to be somewhat fearless in making contributions i feel that a section on cost is another way to add context to the understanding of the size of a terabyte since this measurement terabytes is most commonly used with reference to disk drives and since there is already a section on disk drive capacity it seemed reasonable that there should also be a context to show how the cost of that capacity has changed over time does that make sense now if i could just remember how much i used to pay for a box of punched cards
