This is just plain wrong. I wonder where do you find b/s like this (maybe
post the actual link with such misinformation so we could try getting it
corrected or removing it if it's some wiki?). Unless your controller is built
to use an onboard PMP (port multiplier), there is no such thing as 3 Gbit/sec
controller-wide limitation. But of course it's still limited by whatever bus
it sits on, if it's a narrow PCI-E 1x, that might well come into play.

With respect,
