Asus company decided to revive the idea of motherboard equipment with SATA-600 controller from Marvell production . The new motherboard asus P7P55D premium on base of Intel p55 chipset obtained this controller itself in combination with the chip PLX PEX8613, which solves the problem of PCI expresses bus capacity, necessary for the work of Marvell 9123 controller .
PLX Chip doubles the PCI express x1 capacity to 500 Mb/s, which correspond to the second generation standard. However, if we connect the Marvell controller to the PCI express x1 bus first generation, then it will become the bottleneck for SATA-600, after limiting the effective data exchange rate .
Two ports with SATA-600 support has light grey painting, there are six ports SATA-300.
