Does combination of SSD and HDD require special Hardware?

I'm looking to buy laptop with i5 quad-core and 8GB RAM that has SSD and HDD. I found Lenovo that has all of this except HDD. The model that do have SSD and HDD comes with i7 and 16GB RAM.

You can find HERE both of this models.

I was wondering if this is the only option to get what I want or I can add SSDHDD to any laptop (of course only if it has the space for the device)?
