Serial ATA (SATA)存储技术是一种用于连接主机总线适配器到存储设备如硬盘和光盘驱动器的接口，它以串行方式传输数据，提供更快的数据传输速率及更强的可扩展性。
The SATA (Serial ATA) interface is designed to expand and eventually replace the parallel ATA interface, which has been the standard for hard drives and CD-ROM/DVD drives in personal computers for nearly two decades. As a high-speed serial version of ATA, SATA maintains compatibility with software written for traditional ATA implementations, making it easier to transition to this newer technology. New advancements in SATA include features like Native Command Queuing, which enhance overall drive performance and reliability.
The latest iteration of SATA (referred to as SATA II) introduces additional capabilities such as higher transfer rates, Port Selectors, Port Multipliers, and enclosure services. These new features simplify the creation of low-cost yet high-capacity storage subsystems for server applications.
This book offers critical information for systems engineers, system validation engineers, hardware designers, and software developers. It provides background on ATA to help readers understand Serial ATAs implementation. The text delves into detailed explanations about the serial protocol, commands, and electrical interfaces using a tutorial approach with numerous illustrations, tables, and examples. Additionally, it serves as an accessible reference guide for quick lookup of essential information.
