now the USB 3.0 speed is 5Gb that's mean same speed of PCI-E 2.0 , but i see there is an USB 3.0 control use PCI-e x1 , so is that can handle this much of speed

PCI-E 1x 1.1 is limited to 125MB/s a second each way. Some people call that 250MB/s, but its wrong.

For a USB 3.0 port to run at 600MB/s, it would need to have 4 lanes of PCI-E 1.1 bandwidth for each port on the card. so that means a PCI-E 16x card could have 4x ports on it.

While most consumer motherboards have PCI-E 2.0 for the graphics cards slots, the extra 1x and 4x slots tend to run at the 1.1 standard.

USB3.0 wont be so hot in add-in cards - it'll utterly destroy USB2.0, but it wont show its potential until its integrated into the motherboards directly, and has access to more PCI-E lanes.

they should have put usb networking into the protocol like firewire has got and it could be used as a cheap network made with usb cables and a usb hub or for file transfers from pc to pc.

even HDMI has networking these days :wtf:


the problem with USB networking is rather simple: people would have 10 or more USB network cards appear in windows, and be totally effing confused. so many people have trouble with just wired and wireless, adding more into the mix causes issues.
