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 a
a 5-volt signaling requirement, high pin count, and serious cabling headaches.
he Serial ATA specification is designed to overcome these design limitations while enabling the storage interface toT
