How to determine if a controller is true hardraid or fakeraid?

I've just bought a new SAS/SATA controller (Highpoint RocketRAID RR2720SGL) and it looks like it is hardware raid, but I've no idea how to tell if it is true hardware raid or yet another fakeraid controller. (I don't care as I'm using softraid at the moment, but when I rebuild it would be good to use true hardware raid if it is available.) What I can't tell is what I need to look for in the specification to know which it is, since I've never seen a controller admit to being fakeraid. Is there a key word I should be looking for, or do you just have to suck it and see?
