    You actual read/write throughput seems very low. I'm no expert on the spread of such figures but I just tried copying a large file from my HDD to my HDD (internal) and that ran total around 50Mb/s. I'd suggest exploring that, using a simple copy operation, making sure before you start nothing else is happening.

    Compare that with the same operation on your other disks.

    Have you checked the SMART params? (E.g. Crystal diskinfo, free).

    Okay so these tests were very interesting. I copied a 2 gb folder from my SSD to the HDD and the disk time was 100% and would remain there even after the process said it was done. Took about 1 minute for the disk to return to a normal state where I could watch videos again etc. Of course comparing this to the SSD was night and day. I tried to run the read write tests with Crystal Disk and it took so long compared to the SSD. I couldn't even get a number because it felt like the program wasn't working.

    I ran the actual program itself and these were the results. Not sure how to interpret these values or if there are any red flags. I'm starting to think that the HDD is just starting to go. It's from a 2 year old laptop and doesn't seem to be performing well in my computer. Should I consider replacing it?

    Well there's nothing there to suggest replacement.

    I suggest you try copying a large file between only your HDDs using file explorer, and watch the throughput with Resource Monitor as before.

    If there are differences in throughput between your disks, you could try swapping them round physcally and testing again. Are the all they same type?

    I happen to have exactly the same HDD (with an SSD for Windows + programs).

    I have 2 Samsung SSDs in my computer. OS is installed on the SSD. Not sure if I'm testing properly, but this is the result of copying a file from the SSD to the HDD. Then copying the same file from the G to H partition. Write speeds to the disk never exceed 15 mb/s. Again, it takes a little while for the disk to go from 100 back down to 0% usage even after it says the file has been copied 100%. Sorry if this was the wrong way to go about this. Not sure if I'm doing this right.

    Hi, here I am copying a file on the same HDD. I.e. from the disk- to the same disk.
    I've shown both the task manager and the resource manager.

    At the same time as this I could take the screenshot and paste it into Paint without any degradation of performance.

    If I understand your system configuration correctly you have at least 2 HDDs - you can do the same and compare them.

    If different, try swapping their connections and retry.

    Copied the file from the disk to the same disk and here are the results over time. The disk starts out fast and then dips very quickly. I only have one HDD. The others are SSDs and I feel like comparing them would be a massive difference, correct? I'm sorry if I'm missing something here.

    I also came across people recommending to try different SATA slots like you said. If the HDD performs faster in another SATA slot, does this mean that the slot is faulty? What is the cause of that?

    EDIT: Copied from the wrong drives. Fixed the screenshots.

    Is your E/F drive also a HDD? If so, do the same copy from and to it, and report the throughput.

    As regards swapping the drives, it's simply a matter of elimination. If a drive works in one slot but not another, that tends to indicate where the problem lies. Don't forget 'simple' things like cables and connectors either.

    Nope, E and F is another SSD. I'll go ahead and test out different slots and cables in the morning. Getting pretty late here. If the speeds are the same, is it safe to assume that I should look into a replacement? It seems that this is a hardware and not an OS issue. I believe I have everything configured correctly and the right drivers installed.

    Ideally you could also swap the HDD for trial purposes if you have one..

    And you might be able to connect is as a USB drive to check it out.

    I don't have a spare unfortunately

    I do have some spare cables though so I'll mess around with that later and try it in different slots. I'll report back later with results.
