Experience ultra-fast data transfer with our internal extension cable which supports speeds up to 5Gbps, significantly reducing transfer time. Fully backward compatible with USB2.0 (480Mbps), this cable ensures reliable and stable performance across different USB . Constructed with a robust black flat ribbon design, our cable not only offers enhanced durability compared to traditional cables but also allows flexible placement within the computer chassis. This design approach helps in maintaining a neat and organized setup. Attention to detail is critical - due to variations in USB 3.0 port configurations across different motherboards, some connections might feel tighter.
