Connects any eSATA to eSATA device. The eSATA (e standing for external) provides a variant of SATA meant for external connectivity. It uses a more robust connector, longer shielded cables, and stricter (but backward-compatible) electrical standards. The protocol and logical signaling (link/transport layers and above) are identical to internal SATA.
This shielded eSATA cable is certified to perform to SATA 6 Gbps performance standards. Each end is terminated in an eSATA connector for use with external SATA devices and controller ports only.
