Serial ATA

Next Generation Storage Interface

Bereitgestellt von: Hitachi Global Storage Technologies Europe Ltd. / Hitachi Global Storage Technologies

Why do we need a new interface?

Serial ATA was designed to overcome a number of limitations of Parallel ATA. The most significant limitation of Parallel ATA is the difficulty in increasing the data rate beyond 100 MBytes/s. Parallel ATA uses a single-ended signaling system that is prone to induced noise. Increasing the Parallel data rate beyond 100 MBytes/s would require a new signaling system that would not be backward compatible with existing systems.

Hard disk drives, such as the Deskstar® 7K500, 7K250 and 7K80 as well as the Travelstar® 7K100 and 5K100 series currently outrun the 100 MByte/s data transfer rate. As a result, a new interface system has been defined to accommodate the faster processing capabilities of next generation high-speed desktop, notebook and entry-server architectures.
