Hard Drive - Read/Write Speed Cap?

    Windows 8


    I'm concerned with the opening of programs. As listed in the attachment these are the specs on this computer: Dell XPS 8500; i-7; 8 GB RAM; 1 TB HD (Seagate Barracuda - 7,200 RPM).

    Anyone have an idea if this might be a driver issue?

    Have you tried downloading and running Seagates's HDD diagnostic tool (assuming they have one)?

    Ok, it was hard to dredge that info out of it. You have a Seagate ST1000DM003, and it's a SATA-II Drive.

    Is the drive on a SATA-II Bus? Maybe on a slower bus it has limited functionality. I'm reading the Data Sheet for the drive now...

    The Drive has these special features:

    Seagate OptiCache™ Technology
    Seagate AcuTrac™ Technology
    Seagate SmartAlign™ Technology

    I would go to the Seagate Site and see if there are any Programs that need to be installed to invoke these features. At least look them up.

    On a couple of Laptops I had, there was a special Driver from Intel for the HDD, and after installing it, the performance was a lot better. So check your Motherboard too, if you have any Intel Chipsets, you will need the drivers.

    I just re-edited my attachment so it's easier to follow. Please see the following updated links:
    1) Dropbox PDF: https://www.dropbox.com/s/5gfwob672t...0%28PDF%29.pdf
    2) Dropbox Video: https://www.dropbox.com/s/a22w0koift...28Video%29.mp4

    I've run Seagates's HDD diagnostic tool and everything comes back fine. I tried a couple of other 3rd party apps, and it also shows it is fine. I did a fresh install of Windows 8 upon receiving my Dell XPS 8500.

    This must be an issue with Windows 8. My reasoning - I just got a new Dell Latitude E5430 laptop this morning (literally 3 hours ago). I am experiencing the same problem with the hard drive slowing up the machine.

    The Video looks like it is confirming my Suspicions, you may have some driver missing. Since it is a DELL system, there should be a Chipset download, they use Intel Chipsets.

    Try installing ALL INF files related to the MB, even if it says they are installed, because this kind of behaviour is similar wo then you are running a System without Proper Video Drivers, you know how that is? A System w/o the right Video Driver will do almost the exact same thing. SO I think you are missing something or something did not get installed correctly

    Your Hard Drive should be FLYING, it should go WAY past my 22 mb/s. So you have some kind of Bottleneck in the System, it's got to be in the Data Bus that pulls data from the HDD.

    The only other conceivable thing I can think of is that your HDD is bad, and I don't want to suggest that. But maybe you can try installing Windows 8 to another HDD, and see if it behaves the same way. Did I suggest changing out the SATA Data Cable? Everything points to the Bottleneck being in the Data flow from the HDD.

    I am having the same problems. I just ran disk speed and it shows 4kb blocks being written @ 23mb/s. However, 64kb blocks are being written @ 157mb/s. When I am using disk intense processes my computer will slow down and the task manager will show usage at 100%. It also shows max disk usage around 6~7mb/s.

    That may be something there.

    Is the OS in question a 32 or 64 bit OS?

    He may want to run the same test. Is Disk Speed in the OS or is it a Program I have to download? I wanna check that on my machine.

    I'm running 64 bit.

    Here is disk speed.
    Roadkil.Net - Roadkil's Disk Speed Program Download

    If I run it on logical C: it acts weird. However if it is run on physical 0 it seems to behave more normally. Make sure to run it as admin.

    ALSO: If you want to see something really odd bring up task manager and run them side my side and sort by disk usage and watch the percentage usage at the top and then look at max usage by program which is displayed in mb/s.

    I found HDtune Trial, it says the best my drive can do is 40mb/s.

    I'd like to see his HD Bench from any of these programs, it may tell a different story than his Resource Monitor.

    I also found that when downloading games on my laptop it would act like it was being bogged down. My windows 7 desktop was never like this. Granted it is much more powerful and has 7 hard drives, but a when the disk is being used it shouldn't affect he performance of currently running programs stored in ram.

    Just to point something out about windows 8 as well: I have built 3 desktops running windows 7. My parents have a laptop runnig windows 7. Not once has any of them BSOD'd. The first Win 8 laptop I had BSOD'd on the first day. The second one I currently have BSOD's if everything isn't perfect. And by that I mean it will BSOD after flashing a new BIOS or installing new drivers. I then have to restart it multiple times to get it to clear. Overall I think these are problems with windows 8.
