Care to enlighten me on this one? A hard drive is fast; a CD
writer is slow (even if the manufacturer claims it writes at
XXx). So the hard drive is going to be hobbled by the CD writer,
right? I have the impression that the "red" IDE connector is for
slow devices, while the blue connector is for bleeding-edge
devices, the numbers computer (re)sellers like to tack on to
their specs: UDMA 133.
