Monitor Hard Drive RPM?

Does anyone know of an app or pgm that would allow one to monitor the RPM of a SATA 3 HDD under Win7?
I have a nearly new Hitachi 1.5GB 7200 RPM HDD that I suspect is slowing it's RPM occasionally. At times, it will read really slow... too slow to be usable. When this happens, there is a definite change in the pitch of the sound coming from the drive. With the low price of HDDs today, replacing it isn't an issue. But I would like to know if my theory is correct.

  1. Not that I know of.
    One of the reasons I stay away from "Green" and "Blue" drive. I've also not bought any that were Yellow Poka dot LOL.

    For the past several years IMy prefernce was WD Blak drive, But last 3 have been the Samsung F3

    For what its worth department, the only differece between a Sata III HDD on SATA III port and a SATA II drive on a SATA II port is in burst speed - In other words almost NO diff. For marketing purpose - WHO would want to say I'm still using Yesterdays standard even Though NO better for HDDs - SSDs different store as Seq read/writes are much better..

    Thanks, yes I know that SATA3 is basically for SSDs and that HDDs are maxed out at SATA2 speeds. But the drive was on sale, so I bought it anyway. Maybe now I know why it was on sale...
    I stay away from green drives too, and would never use one for a boot drive. But I didn't know the blue drives had issues too?
  3. I'm not really sure about the "Blue" drives either, I just shy away on general principle

    Very interesting article, but you'll have to explain to me how this relates to my situation. The Hitachi drive I purchased ( http://www.newegg.com/Product/Product.aspx?Item=N82E16822145520) wasn't a green drive or blue drive.
  6. hard drives of all types will spin down when not in use.
    this can be a windows setting, under power management,

    i have not see any software that shows current RPM speed of a HDD tho.

    use something like PC Mark Vantage or IOMeter and compare it to some of the results here if you have speed concerns.

    clutchc, I don't believe it is possible to "monitor" a HDD's speed via software. The silentpcreview article shows you how to measure the speed using your sound card, a microphone, and Fourier analysis software. The same technique applies to all drives, whether green or blue or black or purple.

    Ahhh... now I get it. Thanks.
