If copy speed is important to you, you can try a different brand of flash drive. I made copies of 972 files contained in 50 folders that take up about 7.5GB of space. Copying to these Netac flash drives takes 57 minutes. To make the exact same copies, it takes 99 minutes on XinwaY, 25 minutes on SanDisk, 18 minutes on Juanwe, and just 15 minutes on Imphomius.
