I solved the problem after few hours searching the internet.
Apparently if you have your DVD ROM drive connected to the Marvell Sata 3 ports it effects the SSD connection.
However after I rebooted the computer and the Samsung magician software showed that the AHCI was activated and the SATA 3 is connected I got much lower benchmarking results compared to the Intel SATA 2 ports.
On the Intel SATA 2 ports using the Samsung magician software my results were:
Sequential Read: 281MB/s
Sequential Write: 192MB/s
Random Read (IOPS): 41129
Random Write (IOPS): 31405
On the Marvell Sata 3 port my results were:
Sequential Read: 187MB/s
Sequential Write: 124MB/s
Random Read (IOPS): 29084
Random Write (IOPS): 20765
It is a huge drop in performance when it is supposed to increase my performance between SATA 2 & 3
Can anyone instruct me on how I can improve my performance please.
