    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.

    they were asking for this... https://geeks.com/collections/best-...h-speed-usb-3-0-hub-windows-mac-os-compatible so that they did not have to search the page for it. Common courtesy when listing a hot deal really.

    What is the speed of an external ssd when plugged into usb 2.0 port?

    Iam using several usb keys to transfer movies and stuff from one to another pc but it takes forever to transfer for example one 10 gb movie. Will buying an external ssd solve my problem. I see that its connected with pc via usb cable. What speeds will I be able to achieve? On one pc I have only usb 2.0 ports and on the other one I have usb 3.0 ports.
