All other things being equal(ish), does a higher hard drive capacity generally mean increased power consumption?
I'm looking at Hitachi notebook drives and want to maximize battery life. Does anyone have any power consumption information regarding the Hitachi 5K160 vs 5K250? Which drive (the 160GB or the 250GB) will give me the best battery life?

what you need to determine is what RPM the drives are ... most early laptop drives were as low as 3200rpm then they climed to 4200 ... and most are now 5400 ... 7200rpm for high end desktop replacement types ... the faster the drive spins the quicker it transfers data ... and the more power it uses ... 5400 is a nice compromise

No, the RPM has the biggest effect on the power consumption. Since drives are obviously subject to friction/heat, a 7200rpm drive will require more power than a 5400rpm. The capacity usually is dictated by the density of the data on each platter. True, bigger drives can often have more platters/weight for the motor to spin, but it's generally negligible as their also usually thinner!
Go for that 250GB if cost is no object!

First get the best battery. Most latops on full performance run 2 hours on a battery, 4 , 6 on battery saver. But with the Litheoum battery, 9 hours on performance.
Bigger hard drive--actually better, run cooler, run faster.
