    I'm getting very inconsistent transfer speeds on a USB 3.0.


    As you can see from the images, i am getting these moments where the speed drops to 0 for about 10 seconds then picks back up to full speed again. It reminds me of a 'saw blade' or 'thread' lol.

    I am transferring from an SSD.

    I would download HD Sentinel and check the external and internal drives' health.

    This is normal.
    Smaller sized files will slow down the speed, especially if there are many one after another.
    A larger sized file and the speed will increase.

    Flash drives are usually not the fastest devices around mostly due to buffer constraints & the slowness of inexpensive memory. Most flash drives exhibit exactly what your seeing. Won't get any faster no matter what you do other than replace the flash drive with a fast memory drive.

    That's normal when using Windows File Manager to copy files to a USB flash drive, particularly with varying file sizes. Standard USB flash drives are not very fast.
