The level of voltage to the serial ATA is of differential 500 mV, and it's suitable for PC's technical request, and it can save power as well.

Serial ATA connector includes a line of 7 pin signal terminal and a line of 15 pin power terminal. These two lines of terminals can be detached to the freestanding tie-in, therefore, it not only reduces its body size but also enlarge is trans-positional space.

It almost has no potential to fasten the transferring speed of parallel ATA. But for the serial ATA, the transferring speed for its incunabular design is 150 MB/s.
