This USB 3.0 adapter provides the maximum bandwidth possible via the ExpressCard slot, which is about half of the maximum USB 3.0 speed.

"Yesterday I reviewed the Buffalo USB 3.0 PCI Express card which proved to be an extremely capable card, so I wondered if the laptop version would perform similarly. Notebooks, more than motherboards, need USB 3.0 upgrades since even current high-end notebooks come with 1 or 2 USB 3.0 ports. Any entry level or mid-range notebook available in the market right now doesn’t come with any USB 3.0 ports."
