Are you including the power and materials that are needed to build the new hardisk I think that if you include this tow factors you dont contribute to the power conserved because is to much expensive build the new hardisk in terms of Ecology and power. In a extreme case you must include the power used in all derivated procces to get this new hardisk. About linux vs windows boot speed you can configure linux to boot as you want this is not true for windows microsoft, you can for example boot in a non graphic mode and this is faster. but no all is boot speed in my country ther is a popular say "dressing me slowly that I am in a hurry" I think that the boot up of windows is most cosistent because the procces are loaded in a logical order and in ms windows the process are loaded in order to simulate that all is ready when it isn't.
