I would suggest going to the following website:
How to Use Unallocated Drive Space in Windows - dummies
and it explains how to gather your drives so you can use them. The term is "simple" and not "single" and while maybe not as fast or efficient as the other two simple is easier for a beginner.
I would make sure one of the SSD or solid state drives is the boot drive as your computer will run much faster since Windows reads/writes things to the boot drive while running.
In your screen shot disks "0" and "3" do not have a letter assigned so they can't easily be used by the Windows OS. The site above will tell how to fix things.
As noted you need different software to grab the videos off the camera.
