Seagate today demonstrated SerialATA Barracuda V series of Harddisk at the media briefing held at Seagate office. In the media briefing, Mark explains the need for serialATA as a faster more robust interface over the current Parallel ATA technology which is almost a 15 yrs old technology. As we know, in the current parallel HD architecture, we are always thinking of tidying up the PC as IDE cables are wide and blocks air flow in PC system. Furthermore, PATA has a high pin count, high voltage needs and non-scalable performance.
