Although solid state drives don't typically draw huge amounts of power, we still wanted to see how this new breed of SSDs compared in terms of power consumption. Throughout all of our benchmarking and testing, we monitored how much power our test system was consuming using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and under full load on a secondary test drive. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the drives alone.
Power consumption for all of the drives we tested was minimal, with only a watt or two separating the drives depending on the workload. The updated Gen 2 Intel X25-M 160GB technically drew slightly less power than its predecessor, but in light of our test system's total power consumption, the difference was minimal. In a thin-and-light notebook, however, the new drive's lower power characteristics would be welcome.
