Appearance





By the way, these card reader adapters are working, without question. It’s very convenient to use it sometimes as a USB flash drive. The only thing is that the card is somehow insecurely fixed, there is no characteristic click. It may get lost.
Two card tests
After recording
She asked a person to drop some large file onto a card ... Threw it off .. Caution censorship!







Something confuses me the last zeros ... Is this something?) Is it really that bad ?!


As you can see, the card size is about 7600 MB
The recording speed ranges from 4.89 to 6.662 MB / s
Reading speed from 16.6 to 18.05 MB / s
As a result, there is enough memory, no speed (Class 10 was declared. But, if I understand correctly, in real life there are only 6.
And now I think, I’m guessing ... To pity the Chinese or ask for compensation ... What do you think? Though lipstick he has to “shake”
Ps I do not understand this (including flash drives). Only redlightgreen is my hope and support)))
Addition: The seller agreed to return 5 bucks and wrote a letter of gratitude for testing his products)))
