I hope SATA is a serial device and IDE is parallel device even thought the SATA (HDD) device is faster than the IDE (HDD) device. Could anyone please explain why?...

    I can be found either 40 miles west of Chicago, or in a galaxy far, far away.

    SATA = Serial ATA
    IDE = Integrated Drive Electronics aka ATA

    IDE drives are parallel, SATA are serial, but use the same command set (more or less). I think the reason why SATA drives are faster than IDE drives is the fact that the simpler electronics allow for faster I/O rates. A parallel device requires more stuff to filter out cross-talk between the data lines, and they cannot be driven as fast as a serial line driver because the higher the frequency, the worse the cross-talk.
    Sometimes, real fast is almost as good as real time.
