  Hi Chihwahli,
[ That’s why I want to know which card uses 2 bits per cell. ]
Well,
The multi-level cell ( MLC ) is a memory element capable of _ storing more than a single bit of information. _
MLC NAND flash is a flash memory technology using multiple levels per cell to allow more bits to be stored using the same number of transistors.
MLC NAND flash memory has four possible states per cell, so it can store two bits of information per cell.
MLC Flash is used in consumer applications that do not require long term reliability such as consumer grade _ USB Flash drives , portable media players, and Compact Flash cards. _
Luck.
Regards, Alfred.
