Type 2
Black cable. Commonly used in consoles late in zephyr life-cycle and newer. This connected the DVD drive to the motherboard and had a small piece of yellow tape on the side that connects to the motherboard.

Xbox 360 S Light Blue ODD Cable
Used on early trinity prototypes, this SATA cable differed in in terms of the color and in the cable ends. The straight-through side plugged into the motherboard and the 90 degree inverted side plugged into the DVD drive. Interestingly enough, the port on final trinity motherboards is referred to as "ODD_Blue" even though the final cable is red.
