Virtual memory and a SSD are 2 way diffent things!
But, yes, you could get a SSD just for the pagefile, or keep it on a SSD that's running the OS.
However, since the pagefile is written and re-written several times, this could damge the SSD over time. SSD have a limited number or writes, but reads are (almost) limitless. But, I kept my pagefile on my SSD running my OS.
