Note :
The cable of twisted pairs and neighboring line separated individually is not allowed to use for the host interface cable. It is because that the location of signal lines in these cables is not fixed, and so the problem on the crosstalk among signal lines may occur.
It is recommended to use the ribbon cable for ATA interface that cable length is less than 18 inch (46 cm) and cable capacitance is less than 35 pico farad. Also it is recommended to use AWG18 power supply cable.
