You are welcome
Yep, that looks to be the right one... They are sometime also named as 66/100/133 ATA IDE-cable or just simply 80 conductor cable.
Every second wire (conductor) is grounded to prevent data streams to "interfere" with each others.
Post back if you want a more technical explanation.
BTW, I still use a 40 conductor IDE-cable and have no problem to burn at 16x.
