How to Make the Move to USB 3.0
The 2010 Consumer Electronics Show (CES) introduced a bunch of new SuperSpeed USB (USB 3.0) peripherals with more to come. With USB 3.0 promising performance as much as ten times faster than USB 2.0, you'll want to add USB 3.0's digital goodness to your system as soon as you can. So, what do you need to know to make it work? Whether you have a desktop or mobile PC, we survey your options and help you zero in on your best choices.
Who’s Who in USB 3.0 Controllers
At some point in the next year or so, we'll probably see Intel, AMD, and NVIDIA begin to include USB 3.0 support in their motherboard chipsets for both desktop and mobile systems. In the meantime, it's up to third-party developers to make USB 3.0 a reality.
NEC's The One - at Least for Now
The leading player in the USB 3.0 controller game is currently NEC, whose μPD720200 controller chip was the first to be certified by the Universal Serial Bus Implementer's Forum (USB-IF) (PDF link) back in September 2009. NEC’s USB 3.0 controller chip has been incorporated in all of the motherboards and systems that currently include USB 3.0 support, as well as add-on cards that include USB 3.0 support.

Is VIA in Your PC's USB 3.0 Future?
A possible future rival to NEC is VIA Technology, which has released two new products that demonstrate its USB 3.0 prowess: VL810 SuperSpeed Hub Controller and VL700 USB 3.0-SATA controller. Although VIA Technology was once a major PC chipset vendor, its recent emphasis on embedded systems has made it less of a factor in PC silicon. Thus, for the immediate future, NEC is the vendor that makes USB 3.0 host adapters possible.
NEC and Marvell - Different Chips, Different Jobs
Marvell, another chip vendor, is often mentioned in the same breath as NEC, which might lead to confusion over who was responsible for USB 3.0 controller logic. Marvell is the company responsible for creating SATA 6Mbps controller chips found in the new motherboards and add-on cards, such as this ASUS U3S6 add-on card:
Consequently, current motherboards and add-on cards with USB 3.0 and SATA 6Mbps host adapters use controllers from both companies.
