USB 2.0 Performance

Intel used to provide the best USB 2.0 throughput both when running a single drive on a USB root hub, and when attaching two drives to one of these controllers. However, the performance leadership is gone with ICH10, as it no longer reaches the ICH9’s 30 MB/s, and performance decreases a bit when running two drives on a root hub. ICH10 offers roughly the same USB 2.0 performance as ICH8, but ICH9 (which is used for the P35) is the faster component.
