Unique PCIe x4 Bridge Chip for Ultra Performance:
At ASUS, we understand that bottlenecks and performance barriers is just not acceptable when you want a system that can keep up with you.
Typically by using a plain solution of directly connecting USB 3.0 and SATA 3 controllers to the P55 chipset, only 250MB/s can be achieved. To get the full 500MB/s, ASUS utilizes an unique bridge chip solution that utilizes an additional PCIe x4 pathway to remove the bottleneck. With the TRUE USB 3.0 and SATA 6 Gb/s performance, you can truely benefit from the ultra high transfer speeds from the next generation storage solutions.
With solutions from other brands, you will NOT be able to run a CrossFireX/SLI setup if you enable the USB 3.0 or SATA 3 models, whereas there are no such limitations on the ASUS solution.
Don't settle for less. With TRUE USB 3.0 and SATA 6 Gb/s, your ASUS P55 motherboard can transfer movies, music, and backup files up to 50% faster - without sarificing graphics bandwidth or modifying bios settings.
