15MB/minute would reach the rated endurance of a typical SSD in 65 years. And SSDs usually go way past their rated write endurance (unless, of course, they fail for some other reason). So I wouldn't worry about it.
Modern SSDs are easily capable of 150MB/second, which is 600 times more writing than that. So it's definitely possible for write endurance to be an issue. But not at a write rate that low.
