MEMORY CARD 16, 32GB  FAKE

 

Welcome 

I want to warn you before purchasing SDHC memory cards with a capacity of 16 and 32 gigabytes. 
Personally, I made three purchases of these cards and all have a smaller capacity than indicate vendor. 

The cards I was testing the program h2testw_1.4 which can be downloaded here

 www.heise.de/ct/Redaktion/bo/downloads/h2testw_1.4.zip

 
Before testing, remove all data from the card then run the test "all available space" / "Write + Verify!" 
When testing, keep patience, may take 10 hours. 

 

MY RESULTS OF THE MEASUREMENTS ARE AS FOLLOWS.
