I wouldn't be surprised with those numbers.

Kingston doesn't aim for the top of the market in terms of performance. Their goal is low price.

The cards will be specifically designed for sequential read and write performance. As soon as there's anything random in the write pattern, the speed will plummet. Even large block sizes of several MB will have terribly slow write speeds.

You already got a satisfying answer to your very same question: https://forum.armbian.com/topic/7746-is-your-sd-card-a-fake-check-with-sd-insight-android-app/?do=findComment&comment=60946

 

Kingston cards aren't good for the SBC use case anyway and your card is not even 'genuine' Kingston but a fake.
