FIRST LOOK - USB 3.0 in the Labs (ASUS U3S6)
 

USB 3.0 comes via a new PCI Express x4 drop in card called the ASUS U3S6. It features two USB 3.0 ports powered by the NEC D720200F1 USB 3.0 host controller, a PLX Technology PEX8613-BA50BC PCI-E bridge chip and two SATA 6G ports care of the Marvell 88SE9123-NAA2 chip. The new name for the USB 3.0 standard is "SuperSpeed USB " and it is backwards compatible with Hi-Speed USB 2.0 ports. Data transfer speeds are being spec'd at 5000 Mbps for USB 3.0, a significant speedboost from 480 Mbps for USB 2.0.
