So for some reason when using a certain USB 3.0 flash drive in any USB 3.0 port it is taking forever to transfer video files, it took 3.5 minutes to transfer a 178mb file. I have checkd and all drivers are updated I also made sure to set it so the port is always powered and doesn't shut off when not in use. The drive is a 64GB flash drive and it has about 16GB of free space left. It is mostly taken up by pictures, I would say over 30,000 pictures on it. Am I correct in assuming it may be taking so long becuase it is having to find free space within those 30,000 pictures for the video file? Pictures transfer instantaneously tho.
