I have multiple internal SATA 3 drives but only 2 ports. What's my best option?
This is my mobo (asus p8p67 LE (rev 3))
PCI Express 2.0 x161 x PCIe 2.0 x16 (blue, single at x16 mode)
1 x PCIe 2.0 x16 (black, at x4 mode, compatible with PCI Express x1 and x4 devices)
PCI Express x1 2 (The PCIe x1 slots share the bandwidth with the PCIe x16_2 slot.)
SATA 6Gb/s 2 xSATA 6.0 Gb/s ports (gray) by P67. 1 xSATA 6.0 Gb/s ports (navy blue) by Marvell PCIe SATA 6Gb/s controller
Can I hook up 3 sata III drives?
Can I hook up one of these ?PCI-Express 2.0 SATA III (6.0Gb/s) Controller Card
will the pci-express option have performance impacts?

awesome thank you! Did you look at the 3 SATA 6Gb/s ports? there is a color difference, but I don't understand what the actual difference is with those ports. is it just the chip is by marvell? The description says it's a PCIe port so does that take away from the available PCIe bandwidth?
I dont' want to degrade my video card performance by using these ports for other stuff.
It works like this: the P67 chipset supports 6 SATA ports (http://www.intel.com...ss-chipset.html), but your board has 7 ports. ASUS configured it so that the four 3GB/s ports and two 6GB/s ports map to the P67 chipset controller. That leaves the additional 6GB/s (navy blue) port needing a controller, so what they did was put an additional Marvell PCIe SATA controller on board*. That port is definitely using the PCI-E bus, but there is no indication that lanes are shared with the PCI-E ports. And it is worth noting that ASUS straight up tells you that the PCI-E 1x ports share lanes with one of the x16 connectors, so I think they would have made it clear if the navy blue sata port did also.
PATA: 1 x ATA133 2 Dev. MaxSATA 3Gb/s: 4SATA 6Gb/s:2 xSATA 6.0 Gb/s ports (gray) by P671 xSATA 6.0 Gb/s ports (navy blue) by Marvell PCIe SATA 6Gb/s controller
* Note: my explanation above is slightly incorrect. The reality is that the Marvel controller handles the esata port, navy blue sata port, and pata port. ASUS most likely just added the extra sata port because the controller they needed for pata/esata happened to handle it anyway. I think the marvell controller also handles RAID configurations.
Upon looking closer, it appears when 4x mode is enabled on PCI-E x16 slot 2, this disables both the PCI-E 1x slots. I would surmise this is because 2 PCIe lanes are shared between the the 3 slots. So, I'd say this most definitely confirms that the marvel controller isn't sharing any lanes with the slots; otherwise, a similar limitation would exist.Go to the full post
