I needed a 20 Gbps USB-C cable for some file transfers to a portable SSD, but USB-C is such a mess, I had no idea what cables I had were what speed, or power rating. So I ordered some new ones specifically for data transfer and put labels on the ends. Can't go back and do it with my mystery cables, but at least I will do this going forwards.
Sharing this for anyone who may be in a similar boat someday.
