Small question i bought 32G kingstone memory card class10

But when use SD Insight app it can't detect and recognize the company

■is that mean my card is fake??!!

Note

 when use H2testw program it can read and write 30457MByte without error

But !!

THE WRITE SPEED WAS ONLY 6.79MByts/s

And read speed was only 18.2MByte/s

■it class 10 how write speed only 6.7mb is that error or what???!!!

Some one reply me please!

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.
