Interesting.
I get 50MB/s S.Read and 45MB/s S.Write in the same program, with a 7200RPM 100MB/s PATA IDE drive with an AMD 1.3GHz.

Speeds depend on the data size used. If the data is small, just to be able to be handled by the cache alone, then that will not be a true indication of performance.

The better test to run is HDTach 3.0.1.0 and Sandra Lite:

Run them with both systems and then see how they fair. The main thing you're after is "sustained transfer rate", rather than burst.

The fact that you get 65MB/s shows to me that you may be running in SATA II for some reason.

Also note, 300MB/s and 150MB/s are the theoretical bus limits, not the actual drive performances. They have that bandwidth capability if needed, that is all.
