You really can't generalize. It is probably true that the average 7200
rpm drive runs hotter than the average 5400 rpm drive, but when you get
to talking about specific drives, there are 5,400 rpm drives that use
more power than specific 7,200 rpm drives. In the end, power = heat,
and it's kind of become a standard that the hard drive is allocated 2.5
watts (5 volts @ 500ma) because that is both what the drives themselves
had been converging to as a power requirement (even 5+ years ago) and
because that is the maximum spec of power available from a USB port.
And since you are really only concerned with the difference between two
drives, it just isn't likely to be that big of a deal except in very
extreme cases.
However, the cost of the 7,200 rpm drive is likely to be significantly
higher than that of a 5,400 rpm drive.
