Hello I am interested in buying a new computer. My main activity is copying files from the hard drives to removable drives. My main requirement is that the computer be a super-fast copier. Since I mainly use portable drives that support the USB 2.0 standard, I do not need a motherboard that supports USB 3.0 standard, but I want the computer to provide support in all of the bandwidth of the USB 2.0, in other words, that the copying speed should be 480 MB/s. The question is whether upgrading the PCIe to USB 3.0 or 3.1 will improve the speed of copying.
