HDE 2 Port USB 3.0 54mm Express Card
Using this card allows you to change the expresscard 54mm slot into 2 USB 3.0 ports with lightning fast speeds. Moreover, with a USB bus power card, you can connect to the external AC adapter for power supply. Product may not be able to provide enough power to simultaneously power two larger USB devices, such as external hard drives. We recommend limiting connections to a single external hard drive or multple flash drives.
