What does eSATA stand for?

eSATA stands for External Serial Advanced Technology Attachment. It is an interface that allows external SATA devices, such as hard drives, SSDs, and optical drives, to connect to a computer. This connection method is an extension of the SATA standard, which is typically used for internal drives. The "external" in eSATA indicates that it is specifically designed for external devices, providing advantages like better performance and data transfer rates compared to some other external connection types, such as USB.

The term includes "Serial" to denote the serial communication method used by the technology, which allows for faster data transfers than parallel methods. "Advanced Technology Attachment" is a reference to the original ATA interface, which has evolved to include features that allow for higher speed connections and improved efficiency, particularly in terms of power consumption and heat generation.
