I wonder if the power savings going from 4TB -> 6TB could make up for the difference/GB.
Spinning disks still operate at relatively high power (~8W), and I don't think this value would change with capacity (they don't add extra disk heads, I think its just more platters/higher capacity platters).
Pretty much the major cost running servers nowadays is simply the cost of the necessary electricity to run them and the cooling systems.
(Note that this doesn't apply for Backblazes usecase; they fill harddisks up, then pretty much power them down. That is why you can't instantly access your data stored with them)
