Current SSD's dont wear n tear down that fast anymore. In fact they did a test where they had 2 samsung 840 pro 250GB SSD's writing data to each other. It took ~700 terabyte of data before the SSD's died. If you would write 10GB of data every day to your SSD it would take ~70 years to kill it. I doubt much ppl write more than 10GB per day on average to their SSD. Bigger SSD's and SSD's with MLC have even longer lifespan. There is a reason the military uses SSD's instead of HDD's. Expect them to last longer than your HDD unless you are writing a crapload of data each day to your SSD. Pagefiles on SSD are still easily a order of magnitude slower than RAM even on high end SSD's. It shouldnt use the pagefile unless all RAM is already being used i think.
