High Quality eSATA to eSATA External Serial ATA Data Cable Shielded 100cm
External SATA (eSATA) cables are designed to connect external SATA devices to either external SATA ports or internal SATA connectors. Unlike cables for internal applications, eSATA cabling must be shielded. The eSATA connectors are keyed differently, to prevent the use of internal SATA cables in external applications. While internal SATA connectors have an "L" shaped key, eSATA connectors use smaller, vertically offset keys.
