    Slow HDD read and write speeds

    Hi,

    Thank you for writing to Microsoft Community Forums.

    We will require a few more information from you to help you further with the issue. Please reply with the following details:

    • In which device are you facing this issue?
    • Are you using an external HDD or internal HDD?
    • Are you getting the read and write speed issue on any particular application?

    However, you can Disk Defragment on your computer to optimize the drive. To run Disk Defragment please follow the steps from the article

    Defragment your Windows 10 PC    .

    Alternatively, you can check for the read and write speed of the HDD in task manager. Please follow the steps mentioned below to check the read and write speed of the hard drive:

    1. Press Ctrl + Shift + Esc key together on the keyboard.
    2. Click on Performance tab.
    3. Click on Disk 0.
    4. You will find the Read speed and
      Write speed       at the bottom of the window.

    Hope it helps.

    Please reply with the status of the issue, we will be glad to help you further.

    RANDOM read and write speeds too low

    Two USB 3.0 drives and a USB 3.0 flash drive have reasonable to good sequential read and write speeds. But the RANDOM write and write speeds are awful, up to 200 times slower than the sequental speeds. I test with DiskMark from CrystalDiskMark. I
    tested both with drives directly connected to PC 3.1 USB port and via a 3.0 USB Hub.

    Results:

    Seagate USB 3.0 Disk drive: Sequential read approx. 140 MB/s, Sequential write approx. 140 MB/s, Random read around 1 MB/s, Random write around 1.9 MB/s

    My Book USB 3.0 Disk drive: Sequential read approx. 230 MB/s, Sequential write approx. 38 MB/s, Random read around 1.5 MB/s, Random write around 2.2 MB/s

    Sandisk Extreme GO USB 3.1 Flash Drive: Sequential read approx. 190 MB/s, Sequential write approx. 140 MB/s, Random read around 7 MB/s, Random write around 2.5 MB/s

    Since this happens on different devices my guess is the problem is with the computer and not with the devices. For each of these devices the policies are set for faster performance.

    Drivers are the best Windows can find (when updating drivers via Device Manager).

    What can I do to resolve the very slow RANDOM read and write speeds?

    Why is my HHD read and write speeds so low?

    low write speed

    when I download an app of any platform i.e Microsoft store or steam, I am getting high download speeds but my write speed is only at 2mb/s meaning that it is just slowing down my updates and downloads. I have searched for answers and I cant find anyone with
    the same problem, most of them have low disks speeds and their usage is at 100% but I have low disk speeds and I have only seen my usage go up to 3%.

    this picture is during a 36GB download off the Microsoft store and as you can see, the write speed is low.
