Lets say you have the misfortune of USB 3 ports only on the back of your computer, out of reach without either pulling your entire computer or desk out of the way to get to it. If I were to purchase a USB 3 cable to bring access to the front, would it be slower than just plugging the drive into the port directly? I would also like to know how it applies to USB 2 ports with a USB 2 cable.
