Ditto. My (10gb/sec, 35W) USB-C cables are all white; my Thunderbolt4/USB4 ones (40gb/s, 130W+) are currently all black. smile

I use NVMe drives in external USB4 and USB-3.2 enclosures for quick backups of my main NVMe-equipped laptop. Either is quick, but the USB4 (40gb/s) ones finish in less than 1/3 of the time of the USB-3.2 (10gb/s) ones.
