USB 3.0 is starting to pick up traction, but motherboards are still using third-party chips to add the fast blue port to systems. Intel officially won't be in the game until its Ivy Bridge processors are released next year, along with the associated chipsets that come with them.
Expansion cards also exist for older systems that offer two USB 3.0 ports, but these tend to be PCI-E x1 2.0 cards. As such, they'll only offer a theoretical maximum of 4Gbps, 1Gbps less than the maximum speed of a single USB 3.0 port. In theory, with both ports operating full tilt this could mean the bus gets saturated before reaching maximum potential.
In practice this is barely an issue. Our testing has showed that USB 3.0, like USB 2.0 before it, isn't actually capable of the speeds it touts. Divide 5Gbps by eight and you get 625MBps — a pipe dream compared to our highest speed to date of 254MBps over a single port.
