    I know there is not much difference in power consumption between the two speeds but is there a noticeable difference in heat and noise generated by a 7200 rpm drive compared to a 5400 rpm drive?

    I heard the 7200 rpm hard drive consumes more battery life.

    yup some 7200rpm drives run hotter and noisier but the new seagates I heard consume just as much as a 5400 drive with little or no noise difference

    Tom's Hardware's 2.5" HDD charts include the Seagate 7200.2.

    You can compare the idle power and maximum power with other drives and draw your own conclusions. More electricity in = more heat out.

    The biggest cause of notebook HDD noise is the head movements, not the drives rotation. Some Hitachi and Toshiba HDDs are relatively noisy while, in my experience, Samsung and Fujitsu HDDs are relatively quiet.

    This may answer a few questions.

    REalistically, there is minimal difference in terms of power consumption, with the 5400 sparing a few minutes at best.
