How to select SD card supplier?
Why do you ask for the same capacity card when you make an inquiry, but the price varies a lot?
Please note the following:
1. the sd card is full capacity, but its material has some flaw, we say it is Bad Block, Bad Block will STOP card memory function.
2. bad block rate is higher ;
3. compatibility is not good ;
4. quality is not steady, worklife also not sure, maybe few days, but also maybe few years
This is why some cards have real capacity, but the unit price is much cheaper because of its intangible defects,
Please select according to the demand before ordering.
Business integrity comes first.
