Although Intel isn't exactly eager to jump on board the USB 3.0 bandwagon just yet, that doesn't mean consumers can't get in on the SuperSpeed USB action. While Asus just unveiled the first motherboard to support USB 3.0, the company also snuck out a nifty expansion card for PC enthusiasts who just don't feel like swapping out the motherboard.
Enter the Asus U3S6, providing two tasty USB 3.0 ports and two SATA 6 Gb/sec. ports across the PCI-E bus. Maximum PC took a few zesty screenshots of the expansion board, and reports that it contains three primary components: a NEC D720200F1 USB 3.0 controller, a Marvell 88SE9123 SATA 6 Gb/sec. controller, and a PLX PEX8613 (also found on the SATA6 boards).
According to Maximum PC, the expansion board worked on par with the USB 2.0 ports found on the P55 used in testing. However, because USB 3.0 is relatively new, the site didn't have any 3.0 devices handy; they didn't have a SATA 6 Gb/sec. drive for testing either. However, the site did say that Asus alleviated any possible bottlenecks by running the card in an x4 PCI-E mode.
The Asus U3S6 PCI-E card is expected to be available soon, and will retail for a measly $30.
