If you have a 12GB page file, that means you have 12GB of physical RAM. At that amount of RAM it is debatable whether the Page file is even useful.
I would just set it as as small as it will go (think its half a GB) on the SSD, then make a 12GB file on the HDD. That way you still have the page file if you need it, but it isn't taking up precious SSD space.
Or get rid of it entirely (still will have .5GB though). As I said before, there is some debate as to whether you even need it with 8+GB of RAM.
