How to Upgrade a USB Drive
If you have a computer that doesn’t have USB 3.0 connection, it is possible to upgrade your hardware and install USB 3.0 equipment.
1). Power down the computer, remove the cables running into the system and unscrew the Phillips screws along the rear of the case.
2). Slide the case open to expose the interior of the computer. Look towards the rear of the computer. You will see the large motherboard, which has horizontal PCI card slots. These slots hold hardware cards, including the USB 2.0 card.
3). Push down the plastic levers that are located on both sides of the PCI card slot where the USB 2.0 card is housed. This unlocks the card from the computer.
4). Slide the card out and then insert the USB 3.0 PCI card. Push down on the plastic slots to lock the card into place.
