Thinking thermally, I would guess that less memory would take less power to drive.
While technically true, in practical terms that is not the case.
Larger capacity memory chips do consume slightly more power when idle, but this increase is less than proportional. Doubling the size my increase the idle power by 20% or less. Much more importantly, the idle power is such a small part of the big picture that it can be ignored.
The active power of a memory device can be up to 500 times greater than the idle power. In a typical day of use, how much power is used by the solid state disk drive will be dependent almost entirely on how much data is read or written, NOT on the size of the disk drive.

P.S. The above analysis applies only to solid state hard drives, the type you find in a iPad. It does not apply to rotating media disk drives, the type that are found in desktops and most laptops.
