ESATA

Data-only interface for external storage devices

External SATA (eSATA) is a variant of the Serial ATA (SATA) interface designed for connecting external storage devices to a computer. Standardized in 2004 by the Serial ATA International Organization, eSATA defines connectors and cables electrically distinct from internal SATA in order to make the two physically incompatible and to meet the more demanding requirements of external use.
