Can anyone explain to me why I am getting a max transfer speed of 3MB/s on USB 3.0

I honestly thought USB 3.0 was suppose to have higher transfer speeds. I may be wrong though.

I am transferring game files from my desktop onto a USB flash drive. I get anywhere from 3 MB/s to 0 KB/s. I know the USB port is 3.0, and I think my flash drive is USB 3.0 because it is painted blue just like the port on my case.

Here's my USB flash drive: https://www.amazon.com/EP-Memory-Gorilladrive-Flash-EP-GDUSB/dp/B00GH18HW4

Here's my computer: https://pcpartpicker.com/list/GBPb7P

Thank you!

That is a USB 2.0 drive.

It is slow, USB 2.0 maxes out at about 40MB/s in the real world... Your drive isn't even coming close to that.

USB 3 is in another spectrum with max speeds over 600MB/s

from the amazon page you linked
"Metal attachment loop with the capability to secure the cap when Drive is in use
Hi-speed USB 2.0 interface"
the interface is 2.0, the flash memory itself may just be really slow.
skimping on high speed flash is rarely a good deal, they will use slow/older chips on a faster bus.
