It looks like the SATA interface is capped at SATA 1.5 speeds. Maybe check with Mac to see what the SATA specs are.

Any idea how to check i think mac book pro mid 2009 use sata 2 ?

Even if it came as a SATA 2 spec it might still be gimped to 1.5. The only way to find out is to dig into documentation or call Apple customer support.

The other thing is your AS Benchmark is showing a pciide driver. I don't know what controller that relates to but all benchmarks I've seen with it show poor results.

now i made few tweaks but still very slow performance apple dont deal with windows os only mac os x so its useless to call their support ;[

any idea how to change pciide driver ???
