    I do not know whether my old interal sata harddisk is sata I or II. I was just wondering if this matters at all if I slam it into an external USB cabinet? Wouldn't the bottleneck be the USB connection and not whether or not the interface is SATA I or II?

    Yes. USB 2.0 is far slower than either SATA-150 or SATA-300.

    Firewire is faster than USB, but still slower than SATA-150

    Essentially, you can quit worrying about the SATA-150 vs 300 speed difference, because the disk platter itself can't keep up with SATA300, so there is little or no difference in any case.

    Yeah.

    Drives can barely saturate SATA-150 as it is, making the difference negligible even inside a tower.

    It certainly won't matter on a slow external bus.
