SSD Performace ?

Have a older computer and just installed a Samsung SSD. The computer only has Sata2 ports so my performance is limited. Here is my benchmark before a new Controller Card,I just installed a Satalll (6gbps) 2-port PCI-Express Controller Card. My benchmarks went down? Did not expect this. Any suggestions on this.





New Benchmarks

I have seen these effects before. Apparently a lot gets lost in the PCI-e setup.

It was not that much money, looks like back to Satall
