Development Background
Serial ATA was developed to meet the demand for both faster speed and higher capacity storage drives that keeps on increasing along the digital revolution. With a higher data-transfer rate up to 300MBps, Serial ATA is a natural replacement of the Parallel ATA which could only support data-transfer rate up to 133MBps. The micro SATA connector is designed to enable connection of slim 1.8” drive of form factor 54mm x 78.5mm x (5mm or 8mm) to the Serial ATA interface.


Markets and Applications
Mobile Computing – Notebook PC – Sub-notebook PC Emerging Trends – Set Top Box – Game Console – Solid State Drives
