X220 - Expresscard 2.0 Support / Full Super Speed USB 3.0 (i7) Support?

Hello there,

 

I'm interested in finding out more about the X220 - In particular the actual bandwidth available to the i7 Version of the X220 with it's USB 3 port.

 

I'd like to be able to use the Black Magic Design Intensity Shuttle with this laptop, however it requires a Super Speed USB 3.0 Port.

 

It's common for laptops to only use a single PCIe lane interconnect, giving the USB3 Port only 2.5gbps of available bandwidth. This won't be enough to allow that capture card to work :smileysad:

 

A similar situation also exists for the Expresscard slot - To be able to support Expresscard v2.0, It needs to provide 5gbps (2x PCIe v1 lanes). If it does this, It's possible I can buy an USB 3 Expresscard which will have enough bandwidth to use the card.

 

In short I would like to know if the super speed USB 3 port can actually function at the intended speed, and is not crippled to half rate.

Just following up this post since I bought the actual laptop, I can confirm it does have expresscard 2.0 support in theory (it has a pcie 2.0 x1 port), but more importantly to me it has a super speed USB 3.0 port, running on a PCIe 2.0 x1 lane. Great news!
