Just try attaching the same drive to a USB 3.0 port and see the difference. Many people change their PCs to overcome this limitation. However, you can save hundreds of dollars by using your PCI Express slot. There are expansion cards available in the market which can have USB 3.0 ports and you can insert them into your computer’s empty PCI Express slot. Usually, they contain two USB 3.0 ports.
