    I have a MacBook Pro, the original version from 2006, and I want to put in a larger HDD.
    System profiler says that the SATA interface for the HDD is only 1.5Gb/s, and I know that most newer drives are either 3 or 6Gb/s, so will a newer drive of 3Gb/s work?
    ifixit has a 500GB 7200RPM that they claim will work in "all MacBooks and MacBook Pros" but I am worried that the older and slower SATA bus speed will not be compatible. Thoughts?

    It is backwards compatible. It'll just negotiate at the slower speed (the same way USB 2.0 is backwards compatible with USB 1.1/1.0).

    Awesome. I figured as much, but wanted to be sure before I spent the 80 bucks for the new drive. Thanks.
