related question: given plummeting prices per GB for raw storage, I'd have expected the cost of hosting storage to drop per GB as well, and yet we haven't seen a commensurate drop, even given competitive pressure. What gives?

Yes, I know there's many other costs but I'm talking about * PER GB * and just for storage not access. A disk drive roughly takes the same amount of space/power/cooling regardless of capacity, so if you install 2x larger drives then cost ** PER GB ** should fall in half. And yet, we haven't seen that among cloud providers.

This should mean that inactive accounts quickly drive to near-zero cost, since they're nothing but storage capacity. Photo hosting should drive to zero. etc etc etc

Can anyone explain ??
