It's NTFS since I occasionally need files >4GB. I ran checkdisk to see if there was anything wrong, but there wasn't. The flash drive is NTFS formatted, but it used to be FAT32.None are broken, and none ever show any signs of being slow. USB port is also 3.0, and I've also tried every single other port in my computer.It reaches about 120-130 MB/s during the copy until the final point where it still says 130 MB/s but does nothing for 30 seconds. The flash drive I mainly use is USB 3.0, quite new and easily capable of ~150MB/s writing speeds.
