This cable connects your Serial ATA devices to your motherboard or host controller. When connecting serial ATA devices to your motherboard or host controller, the last thing you need is a cable that could fatigue, or even fail over time, because of bending or stress occurring right at the connection. Our angled connectors deliver the cable at a more desired angle and are fortified to keep the cable lined up straight. So you will see less cable bend and fatigue for longer cable life.
