Connecting an external Video Card to my laptop.

I have a Dell Inspiron 17R 5720, and I wanted to know if I could connect this adapter to my laptop:

Actually the question is do I have an ExpressCard slot in my laptop? I don't really understand this stuff but

I know I have a SD Card slot... it is the same as an ExpressCard slot?

And If it's not, maybe there is another PCI Express slot inside my laptop that I can connect it to?

Thanks.
