Hello,

I read somewhere that the ExpressCard slots of the laptops could be attached (internally) to either a USB header or directly to the PCIe bus.

I have an external hard drive that can be connected with either USB 2.0 or a eSATA II. The eSATA should be much faster but my laptop does not have a eSATA port. I am thinking of buying a ExpressCard 34 card that will give me a couple of eSATA II ports but if the whole ExpressCard system is attached to the computer using USB then it defeats the purpose.

Is there a way (other than openning my laptop) to find if the ExpressCard system is attached to USB or directly to the PCIe bus?

My laptop is Lenovo IdeaPad Y430-5232U (link).

Thank You!
