    HOWEVER... I then copied the same 16GB backup file from the desktop TO the USB stick... and...
    ...the horror, the horror.
    I've noticed something similar, but in general and maybe not even confined to USBs. There's a burst at first, then things slow down. Some buffering effect, when the buffer gets full?

    [OT: did you know there was a sorta real Col Kurtz?]

    Cache getting filled and drained, filled and drained, etc. Depending on the individual controller and components.

    Conclusion: nothing is simple. Ever :)
    Exactly. However it really should not be a surprise a heavily worked drive would get hot.

    BTW people obsess over the heat of NVMe drives when they reach mid 40's, because someone posted their temps were below 30. They don't realize that as long as the drive stays below 80 Celsius, the mid 40 degrees is a non-issue. Instead they obsess over 40 because someone said the temps should be below 30

    Peace

    Yeah, I've noticed that as well. That's some Windows 10 thing. :/

    I copied 1300 pics from HDD to desktop (SSD). Continuous speed about 350MB/s.
    Then copied those same pics from desktop to USB stick...



    Started out at 300MB/s then....

    It seems copying anything, any size from Windows to storage, bogs down seriously, after a while.
    It's probably Windows trying to spy on everything you're trying to copy to storage.




    And yeah, there were quite a few Col. Kurtz types in Nam.

    The other thing to remember is transfer speeds are rated as "up to" instead of "Guaranteed". That's because manufactures realize there are a myriad of things that can influence transfer speeds to include file size, hardware, software, PC configuration, and background processes, just to name a few.

    And just because I got high sustained speeds doesn't mean you will... as said PC configuration will definitely influence efficiency of transfer speeds - again, "up to" not "guaranteed"

    That said, if your sustain speeds are really low, you might look at what's going on with your PC. Usually the first thing to look at are the chipset drivers for the motherboard.

    Good luck.
