"I think I'd avoid doing a torture test of a disk drive of any type, but especially an SSD. Technically you are wearing out the SSD which has a finite number of write cycles before it will stop working on you. Problem is, you don't really know how many cycles an SSD has
If the kind of wear and tear you can create in a few hours or a day of stress testing is significant then your drive is severely flawed. As far as knowing how many cycles it can withstand, it's called a spec sheet.
