Serial ATA to External Serial ATA Dual Port Adapter Converts 2 internal SATA connectors to the new External SATA connectors
The new SATA to eSATA Dual Port Adapter from Cables To Go adds external eSATA ports to any Serial ATA controller. This external eSATA slot plate adapter allows you to take the high speed of SATA outside your computer case.

Just install the adapter plate into an open I/O slot on your computer. Then connect the cables to the Serial ATA connectors on your motherboard or SATA controller card. This will allow you to connect external SATA drives that use the new eSATA connector.
