Sigh. I'm pretty tired of debunking this, and I'm copying exactly what I said previously
The idea that SSDs are fragile snowflakes that will melt under the
white heat of data is a bit of a mistake.
Many tests have been done where drives have been torture tested - tech
report did one with last generation drives, here's an ongoing
one and basically its PRETTY hard to kill a modern SSD by
excessive writes.
If it dies prematurely, its more likely to be due to other things.
You're going to want your pagefile on a SSD - If you have tons of ram, you're barely going to touch it except when needed.
If you don't, the fast SSD will be a better place to put a pagefile.
I tend to treat my systems as if my drives would die any day, and back up so... I'm probably a little less worried, but I'm doubtful it'll have a major effect on drive lifespans

I found this gem
Should the pagefile be placed on SSDs?
Yes. Most pagefile operations are small random reads or larger
sequential writes, both of which are types of operations that SSDs
handle well.
And quite a bit more - its worth a read on the source.
In essence the things SSDs are good at (fast reads) and the sort of files that use a SSD efficiently (large ones) are both what the pagefile is.
The even go on to say
In fact, given typical pagefile reference patterns and the favorable
performance characteristics SSDs have on those patterns, there are few
files better than the pagefile to place on an SSD.
So. Microsoft recommends using your SSD for your pagefile.
