No se a que viene lo de PATA porque si lees esto:
In fact, Serial ATA does not entail any extra performance in and of itself - contrary to what is often propagated in innumerable marketing brochures. At the current maximum 150 MB/s, only the interface itself offers a good deal more bandwidth than UltraATA at 133 or 100 MB/s. But there are still no drives that can approach the maximum bandwidths of the UltraATA standard. Anyone solely interested in fast transfer speeds can continue to do without Serial ATA - unless you're dealing with a Western Digital hard drive with 10,000 rpm.
que por cierto viene en la pagina que linkeas
verás que si no tienes un disco duro a 10000 r.pm´s (q va a ser que no...) es más potente el ATA estandar, para todo...
