    What is this? I was comparing the Macbook pros and came across that option. What is it? what does it do?

    It's a transfer protocol like USB, just faster (65MB/s) than USB 2.0 (35MB/s) and less CPU intensive.

    You can use it with DV/HDV cameras and many external HDDs.

    Also this could be found via that.

    The max transfer rate of USB 2.0 with a single south-bridge controller (the case with Apple's notebooks) is 60Mb/s, not 35Mb/s. Nevertheless it's still 40Mb/s slower than FW800. The rest is true.

    Those are theoretical maximums, real world bandwidth is always less. FW800 maxes out at ~80MB/s while USB2 lags somewhere around 50MB/s

    I only offered my experience, in which all my USB devices can only achieve 35MB/s on current x86 Macs, and FW800 can get up to 65MB/s.


    Btw, you wrote Mb, which is short for Mega bit, so 60Mb/s is slower than 35MB/s.

    And as Hellhammer already stated, you refer to the theoretical speeds for USB and FW800, which are 480Mb/s (USB 2.0) and 800Mb/s (FW800), which are never reached.
