Is a 7200RPM SATA laptop harddrive really faster than a 5400RPM one.

I currently have a MHW2120BH Fujitsu 120GB 5400RPM hard drive in my laptop. I was thinking of upgrading to a MHW2160BJ Fujitsu 160GB 7200RPM hard drive. I don't really care that much about the extra 40GB. Would the increase to 7200RPM really increase the speed that much? It's only $50, but is it worth that? Would I notice?

Also, do 7200RPM hard drives make more heat or noise?

    I purchased a 200GB 7200RPM laptop drive a little less than a year ago that I used to replace the 5400RPM drive in my PS3. Some things load a few seconds faster, but if money is tight I wouldn't spend the extra $50. Most newer 7200RPM drives are as quiet and cool as their 5400RPM counterparts, and any difference should be unnoticeable. I certainly didn't notice any difference in noise with my PS3 when I upgraded to the faster drive.
  2. Heya,

    It's noticeably faster. It makes more noise. It makes more heat. So it depends on what you need your drive for. It makes a difference because Windows constantly writes to a pagefile unless you disable virtual memory (even in Vista), which constantly slows your drive and everything else your machine does. If you use Vista and you have like 8 gigs of RAM in your laptop, then the slower 5400rpm drive would be fine (and disable page file). But if you have less than that, get the 7200rpm.

    Cheers,
  3. Its not worth $50 for a 40gb gain and minor speed increase, however if the hard drive were bigger say 200GB+ then it would be worth it.

    I feel an extra $30 is worth the extra storage capacity.

    And the performance increase.

    the people reviewing it like it alot.
  4. It's fairly significant. I upgraded mine from a 5400 to a 7200, and stuff is noticeably faster.
  5. Battery life will be a little shorter with the 7200 rpm.
  6. whether or not it is worth the $50 is up to you.

    Performance will increase.

    you can still use the old drive as an external. You can get cases for like $10.
  7. Thanks for all the replies.

    Will battery life be much worse?

    How much can I expect the increase in performance to be? Some reviews say <5%, and some say it'll be ~20%.


    Other than storage space and price, is there any difference between the performance of these three drives?

  8. I'm not familiar with the Fujitsu line, but later model drives will be faster, as they have better seeks and faster sequentials. As for battery life, it shouldn't be significantly affected.
