Although laptops even upscale purchased at the beginning of the year were not equipped with the USB3 nascent technology, and today this type of connector is absent on multiple devices. Of course, USB3 devices can be connected on traditional USB2 connectors and run anyway, but speed very far below what allows USB3 technology. Also the addition of this card will be relevant if the port ExpressCard 34 mobile uses a bus fast enough to ensure a large data stream, close to what offers the USB3; it will generally be the case for laptops which is present PowerOver eSATA connector. This is the VAIO VPCF12 for example, where in 6 minutes 26Go data are copied between the internal drive and a USB3 drive connected to the map! Copying large disk to disk data volumes connected together on the same card is also possible, without dropouts. Of course, the board is powered. To do this, you can use the USB power cable, but it amounts to obscure a USB2 port on the laptop. The alternative (if one is not nomadic status) is to feed the card via a block not supplied 5V (eg HQ - P.SUP.SMP1-BL 661035 or on the same site)
