    Has anyone done a formal battery life test with these drives?

    Sometimes I feel that a 7200 rpm drive will decrease battery life, but that was 2 generations ago. I feel that they really did, but maybe now things have gotten better. Does anyone have hard numbers from real life rather than theory?

    Are we talking about a 5 minute battery life difference or something like 20 minutes or more?
    20 min and I'd notice, but 5 min, I'll take the performance increase.

    It can depend upon what power saving plan you are in and what applications are being run on your system...

    I can't speak personally from using the 7200.4 but from my past use with 5400 and 7200 rpm drives the power draw has been very small in difference between the 2. Were talking around the 10 minute mark at best. I've never been concerned with losing battery performance with a 7200rpm drive.

    A 5400rpm motor will use less power than a 7200rpm motor, however the difference between the 7200.4 and the WD5000BEVT is not very much. The seagate has a higher idle power consumption and load consumption, so battery life will be less. However if you want the most power efficient mechanical drive you can get, it has to be the Hitachi 5K500.B. It has a much lower idle power consumption than the WD5000BEVT, and a much lower load power usage. It peaks at under 2 watts of power, which is about half of what the 7200.4 uses.

    We are talking about 2 minutes per hour of battery difference between the WD5000BEVT and the 7200,4
    We are looking around 5 minutes battery per hour battery difference between the 5K500.B and the 7200.4

    The 5K500.B fares well against the WD5000BEVT, its actually a bit faster in most respects.
