Depending on the drive it may actually slow down IO as the SSD will need more time to finish the IO. Doing an fstrim leaves the processing to the SDD. That was the argument years ago. I don't know if this is still true for modern SSD's. For older SSDs fstrim would stil be the safer option. And automatic trimming is long overdue in my opinion.
