After reading this question about maxing out an SSD I decided to do so myself.

My mobo only supports SATA 2 and has two PCIe 2.0 x1 connectors (which promiss up to 500 mb/s). So after some searching I decided to go with this controller from amazon.

My Samsung magician benchmark before upgrade (running SATA 2):

Now after installing the controller all of the benchmark scores are lower (even though the Samsung Magician app confirms its connected to a SATA 3 port):

What can I do to remedy this? Any help is appreciated.
