From a discussion elsewhere I have the opinion that the reason it isn't default is that some SSD not only don't implement it properly, they may lie and say they do. I have seen "lies about capabilities" in several place, not just WRT TRIM, so I think there is an issue with some brands. I can say that testing using an Intel X25-V worked with the option on. > 4.
