    USB 3.0 transfer speed drops to 0 only on one port. USB port and external drive are NOT defective.

    I have a Dell XPS 13 laptop with two USB 3.0 ports. I connect a Seagate expansion drive to the left USB port and transfer a 4GB test file. It transfers about 1GB at 150MB/s and then transfer speed drops to 0. Then it picks up again after 3-4minutes, then
    drops again intermittently.

    I connect the same Seagate drive to the right USB port. The same 4GB file transfers with a constant speed of approximately 150MB/s. Thus the Seagate drive is not defective. Perhaps the left USB port is defective.

    I connect a Sandisk 128GB flash drive to the left USB port (that is now suspected defective). It transfers the same 4GB file with constant 130MB/s speed, no speed drops!

    Each step is reproducible 10x.

    I am out of my wits here.

  3. Windows 10 file transfer

    You write "the file transfer speed drops to zero", yet the xcopy command does not provide you with any feedback about speed or progress. I suggest you do this to drill down a bit further:

    • Examine the event logger (as mentioned before)
    • Use robocopy instead of xcopy:

      robocopy F:\ D:\ /s
    • Repeat the copy process on a different machine

    SSD/USB3.0 Speed Drop


    When transferring files from my external SSD/USB3.0 to my PC, the speed drops from around 300MB/s to 105MB/s.
    It stays at 300MB/s almost 60% of the transfer, then it Drops.

    What to do so that there is no Drop?

    EDIT: Disabling the "Write Cache" for HDD in PC, the speed drops to around 45MB/s, instead of 105MB/s.
