All X58 motherboards use Marvell as the controller for their SATA 3 ports.
The Marvell controller on your motherboard has a maximum data bandwidth of PCIe x1 at 5Gb/s (500MB/s).
You will not get the maximum advertised speeds from any SATA 3 SSD you connect to the Marvell ports, but your performance will still be better than connecting the drive to one of the SATA 2 ports.
Do not RAID SATA 3 SSDs on the Marvell ports; you will get better performance with RAID on the SATA 2 ports.
Make sure the Marvell controller is in AHCI mode for best performance.
