MY problem:
I have a USB stick (SanDisk Ultra 3.0: formatted on FAT32 ) connected to a usb port which is also a 3.0
I need to move 3gb of data from USB stick to PC
but the speed transfer is always around 400 kb/s not even Mb/s!
it takes hours to transfer 3Gb of stuff

What is the problem and how can I fix it?

I tried to follow some topics here ad I tried:

  • uninstall usb drivers from device manager
  • set the pen drive to "better performance"

If the 3GB is 100,000 small files, then it will be slow because of the overhead of creating all the directory entries. Creating a zip file on the main computer and copying that file to the USB drive would eliminate that problem.
yeah it was propably that. it sucks! is unbelivable that in 2019 I have to wait so much to transfer so little :/
