Notice: We sale original TF card, So the price will be higher than other seller, If you think cheap is the best, Never mind. Because their memory is an expansion card, actual memory simply does not meet their description.
Many expansion cards currently on the market
Capacity expansion is to use 1G or 2G (or 128M, 256M) capacity to expand 4G 8G 16G 32G, etc.
Actually 1G or 2G capacity, buyers can not determine whether to expand capacity through the computer.
Use software to test!
A simple test is to determine whether or not the amount of information is sufficient. For example, a copy of a 14.4G capacity card with 14G or so of data
(Files, songs, movies), then remove the hardware from the lower right corner of the computer and unplug the card reader.
If you can read that the actual capacity has been reached,
The capacity for expansion can be used, and the data copied in later is damaged and cannot be read!
