    So as part of the Intel Sandy Bridge flaw fiasco, I am moving over my hard drives to the SATA 6 Gb/s ports on my Asus P8P67 Pro motherboard.

    Can I use a SATA 3 Gb/s cable to connect a SATA 3 Gb/s device to a SATA 6 Gb/s port?

    Thanks!

    Here are the devices, for reference:

    WD 640 GB (WD6401AALS) - 3 Gb/s <-> Intel SATA 6 Gb/s port 1
    DVD writer - 3 Gb/s (probably less) <-> Intel SATA 6 Gb/s port 2
    WD 2 GB (WD20EARS) - 3 Gb/s <-> Marvell SATA 6 Gb/s port

    Sorry Numenorian, I wasn't sure if you were responding to my post of the follow-up, so I thought I would clarify: I can use a SATA 3G cable with the SATA 6G port, right?

    Yes but don't expect SATA 6G speeds.

    He won't get 6G speeds even with 6G cables.

    Would it be better to use the 6G cables if you have them?

    Won't make a difference on a 3G drive.

    Anomoly, they won't make a difference but they will work. I can confirm as I just switched my sataII drives over to sataIII ports using those cables.

    Currently using marvell for my dvd drive.
