Is all this green technology worthwhile in a NAS? I'm thinking of getting something like a netgear readynas and would be looking to put 4 drives in it. "green" drives like this I would hope would be cooler, thus requiring less fan speed, as well as consuming less power.

would the software on such a device negate the special stuff through? I don't know if all this stuff requires driver/OS support to really be useful?

anyone know?
