As well, which port(s) specifically did you plug them into (USB 2.0 or 3.0)? ** Description changed: Low speed when transferring files over USB 2.0 and USB 3.0. An example device with FAT: Bus 002 Device 004: ID 13fe:4100 Kingston Technology Company Inc. If the USB drive is not empty, the transferring speed is lower. the bigger the file, the slower the speed. Here are my tests: from HDD to USB (FAT): - 1. 450 MB in 4 sec.
