Although hard 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.
There's not much to see here. The OCZ Apex Series drive does seem to consume slightly more power than the other SSDs, likely due to the use of a second controller in the drive, but all of the SSDs use less power than the standard HD, and the deltas between the SSDs are minimal to non-existent.
