SDTEST serial command not working for a while

I meant to reply with this bit for anyone searching the topic so they know why UHS3 is preferred.

UHS is basically “write speed” but it’s also a manufacturer’s metric to the overall quality and speed of the cards. As-in a UHS 1 may write/read at say 10mbps, a 3 will be three times that speed, say at 30. * @NoSloppy feel free to correct me if I missed anything there or if anything needs expanding.

@LyleStyle I was reading the other current topic and just realized, Kioxia isn’t offering the 3’s anymore. :confused: Guess I’ll be going back to Kingston again.
