Actually no, a hard drive could consume 200W and be more reliable than today's are, it would simply have to be engineered to do so with reliability in mind, instead of penny-pinching budgetization. "Green" is no more than a marketing term when they find a way to do something cheaper, or with relatively minor expense.

There is no reason to think failure rate differs, if they don't replace the parts (subcomponents) that fail at higher rates. That's kinda why I made the comment in the first place.
