   @thomasfuchs still kind of bothers me that not all USBC cables transfer at the same speed but you can’t easily tell without trying. The skinny cable that came with my phone transfers so slow compared to a thicker one that came with an external drive I bought.

     @990000 @thomasfuchs These are some of the possible combinations for cables that have USB-C connectors on both sides:

     • USB 2.0 only
     • USB 3.0/3.1/3.2
     • Thunderbolt3
     • Thunderbolt4/USB4
     • Thunderbolt5

     And these can each support either 3 A or 5 A power and either up to 20 or up to 48 V. TB3/4/5 cables are usually marked by having number 3/4/5 next to the connector, but the others typically have no markings. Good luck figuring out what the cable supports!

     @thomasfuchs it’s so confusing because the thinner white woven Apple charging cable is slower than the black thicker cable that I think came with a GTech SSD drive that I got, which is faster. Maybe the thick one is Thunderbolt and the thin one is just USB3.1 or something. I wish you could plug it into a Mac and the Mac would just tell you.

     @thomasfuchs does that mean the two cables I have — despite having the same connectors — could be Thunderbolt and USB4?

     @thomasfuchs They didn’t bother marking which one is USB 3 vs. USB 2 on the new MacBook Neo.
