Idle power draw is incredibly low with the two SSDs, almost reaching the level of a desktop PC. Using several hard drives increased the total system idle power consumption by almost 100 W! Differences do appear with different power supplies, though. Our test results are meant to show that the power consumption gap between a few SSDs and a bunch of hard drives can be large enough to operate an additional system with the saved power.
Putting the drives to work results in an increase of power consumption, but the increase is relatively low.
