Possible to dual boot two separate hard drives?

I just bought a new SSD for my Mac Pro 5.1 and I want to install Windows 7 (x64).

I currently have a dual boot (using Boot Camp) on the hard drive that came with the computer (1TB) with Mountain Lion (OSX) and Windows 7 64 and it is working flawlessly.

Now, what I want to do is install Windows 7 on the SSD, then remove the Windows partition on the 1TB HD so that only OSX is on there. When I start my computer I don't have a preference which OS boots first (pretty sure I can figure this out by using Easy Boot CD). What is the best way to do this? From what I understand Boot Camp only works when you're partitioning ONE hard drive to dual boot. I want to boot off of two separate drives.

Please help!
