USB 3.0 the Real Deal, SATA 6GB Not Yet

Posted by timothy on from the built-for-speed dept.

MojoKid writes "HotHardware has posted a sneak peek at a new motherboard Asus has coming down the pipe with USB 3.0 and SATA 6G support. The Asus P7P55D-E Premium has a PLX PCI Express Gen 2 switch implementation that connects to NEC USB 3.0 and Marvell SATA 6G controller chips. With a USB 3.0 enabled external hard drive connected to a USB 2.0 port and then to the board's USB 3.0 port, there were some rather impressive gains to observe. When connected to a USB 3.0 port, the external hard drive was about 5 — 6x faster versus connecting over USB 2.0, with total throughput in excess of 130MB/sec. On the other hand, benchmarks with Seagate's new Barracuda XT SATA 6G drive show little performance difference but a burst rate that is off the charts. According to ATTO, there are slight overall performance benefits to be had connecting the drive to the SATA 6G controller, but the deltas were quite small; somewhere in the neighborhood of 5MB/s or so."

    We're still trying to pass a gallon of water through the eye of a needle - the sea change will come when we use light to store information and using quntum mechanics we can imprint information on secondary memory systems without loss
