This motherboard comes with a Promise Serial ATA (PDC20375) controller, aiming to provide you an
even faster transfer rate of 150 Mbytes/second. The traditional parallel ATA specification has defined
the standard storage interface for PCs with its original speed of just 3 Mbytes/second since the
protocol was introduced in the 1980s. And the latest generation of the interface, Ultra ATA-133, has
been developed further with a burst data transfer rate of 133 Mbytes/second. However, while ATA has enjoyed an illustrious
track record, the specification is now showing its age and imposes some serious design issues on today's developers, including
a 5-volt signaling requirement, high pin count, and serious cabling headaches.
The Serial ATA specification is designed to overcome these design limitations while enabling the storage interface to scale with
the growing media rate demands of PC platforms. Serial ATA is to replace parallel ATA with the compatibility with existing
operating systems and drivers, adding performance headroom for years to come. It reduces voltage and pins count
requirements and can be implemented with thin and easy to route cables.
