QuoteThe higher speeds of eSATA compared to USB could grow more obvious as consumers try to wrestle with ever-larger quantities of videos, photos, music and other data. "Backing up a terabyte across a USB port would be incredibly painful. That's going to drive demand for a high-speed port like eSATA, said Roger Bradford, who leads storage work for Intel's chipset and graphics marketing group. However, the challenges of eSATA are as considerable as its advantages. First off is the usual chicken-and-egg problem of technology that requires backing from multiple companies. It's not worthwhile for PC makers to add eSATA ports if there aren't eSATA drives, while eSATA drive sales are gated by mainstream availability of built-in eSATA ports.
