This is the cheapest USB4.0 40Gbps high-speed USB-C data cable that I see on Amazon from a reputable brand. Great for connecting your computer or smartphone to video monitors, external SSDs, USB hubs, etc.

If you don't need that much speed, Amazon also sells UGREEN 10Gbps cables for slightly less.
