Connect an eSATA storage device to a USB 3.0 port on your laptop or desktop. The USB3S2ESATA3 USB 3.0 to eSATA drive cable lets you connect any external eSATA hard drive, solid state drive, or optical disc drive to your USB-enabled computer system - a great solution for computers that don't natively support eSATA, such as MacBook and Ultrabook computers.
