It goes without saying that you shouldn't use RES2SV240 with SSDs. Since that's not the case, you're probably fine with the expander. I have the Intel in a 2U 24x 2.5" server and it works great for rotational media. There is a new LSI expander (the Intel uses the Bobcat LSI SAS expander I think) but wouldn't be much help. Get the Intel if you can a reasonable deal on it.
