Do You Need A New Hard Drive With Your Windows 7 Upgrade?

Benchmark Results: Performance Per Watt / Efficiency

Knowing that performance has increased considerably while power consumption has declined, we expect quite a dramatic increase in performance per watt.

Here we go. Streaming sequential data is 138% more efficient on the new drive, which is faster while requiring less power.

Workstation I/O entails high activity of the hard drive heads. As this requires more power, the efficiency difference is not as large here, but it’s still around 50% in favor of the new Deskstar 7K2000.
