    pls recommend a hdd which is > 500Gb w/ low power consumption and good performance.

    i just tried Samsung HM640JJ 640GB 7200rpm, found my laptop battery discharging time is decreased from 3 hrs to 2hrs.... too much!!! :mad:

    i doubt a hardrive can change that much power loss. There has to be something else going on. Though i would recommend an SSD or try WD one. They have some special drive that is 7200rpm but uses the same amount of power as a 5400rpm. Though i have forgot the name of the drive.

    thanks,

    but it happens, comparing with the previous hdd installed (WD5000bevt), samsung hm640jj drain my battery much faster.....

    for a laptop, battery discharging time is also very important because i need carry it outside.............

    update,

    after using Samsung HM640JJ for 10days, i took it out from my notebook, and put back WD5000bevt...everything go back normal.

    i am considering either return the Samsung HM640JJ, or put it in enclosure, or buy another one, etc, WD5000bekt, 7k500....

    did the OP even consider, for a second, that he might have had a bad drive?

    Considering the WD will spin down from time to time, this is not that unusual.

    If you lose an hour of battery power with the 7K500 (versus whatever HDD you have right now) then it is a software/driver issue - not the hard drive that is affecting the battery run time that much. :)

    1. his way of measuring is incorrect
    2. he got a bad drive

    otherwise there is no way that drive can reduce battery life by 33%.
