Overview: The interfaces of Hard Disk Drives (HDDs) have been changed to serial interfaces to meet the demands for high-speed data transfer. Because of the recent demands for cost reduction, however, requests are being made for serial interfaces optimized for the use of the HDD units. As a result, the HDD market segments have become fractionalized, and the correspondence between the market segments and serial interfaces has also been lost. This paper describes the features of these serial interfaces and the interface technologies of the HDD controller that enables serialization of the interfaces.
