    7200 vs. 5400 Hard drives
    Do 7200RPM hard drives get hot easily and use up more energy compared to 5400 RPM Hard drives? (lower battery life) How noticeable are those differences?

    Well, physics applies as always. Yes, a 7200 rpm drive will generate additional heat and consume more power. The differences are not terribly significant in my experience. But you can probably expect a few minutes less battery life as a result.
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

    Read and write speed more than make up for it, IMO.

    In short, in the real world, the extra speed has no real impact on battery life as far as I can tell, and my experience has mirrored that. Heat is the same deal-the 7.2k drives use, at most, a couple tenths of a watt more power than their 5400rpm counterparts. You will never notice a difference between the two drives' heat output.

    That really is the definitive post on this subject. Geeky, you should really consider writing a FAQ for the FAQs subforum!

    Maybe after the treatment program for the carpal tunnel I gave myself writing the RAM guide runs its course
