The average read/write power for the 500GB and 1TB capacities is 1.6/1.7 W, and an average idle power of 0.45 W.
Using a couple of our models in various storage capacities for example, just to get a better picture of what this looks like:įor our 2.5' BarraCuda drives: capacities 500GB, 1TB, and 2TB, startup current specs out at 1.0 A. This is because power management is paramount in laptop computers, so 2.5' laptop drives are going to prioritize power conservation over raw performance capabilities. You're correct, the performance will be different in a 2.5' hard drive than you'd see in a 3.5' counterpart, even with otherwise similar specs as far as things like RPM go.
