I also realised that many "40Gbps" cables will do "80Gbps" speeds just fine.

Tests include:

- Resistance with Alientek OA1 (not sold in western markets yet, I got as a test unit)

- Data Speed with 80Gbps OWC Enclosure and DiskMark on a Macbook Pro M5

- eMarker read (screenshots on the site)

- Thermals after 30 minutes at 100% Power on ATorch USB Load Tester.

I also did a quick summary of my conclusions on 6 USB Testers (see video). Alientek C2, C0, ATorch T3, Fnirsi C2, Witrn K2, Power-Z KMC003C

I hope you find useful.
