The maximum transfer rate of SATA 2 is, ideally, around 300 megabytes per second. You're beating that by 30% in the real world so it really does look like you're getting SATA 3 speeds.

Just because a drive uses a SATA 3 port doesn't mean it's capable of its full 600 megabytes per second, of course. Whether you're reaching the true maximum speed of your drive, I can't say without knowing what it is and looking in its manual. The limits of your southbridge and memory are also important.
