Speed between the chips cyclods and microsd

[Matmat57]

Hello:) ,
I want to know the actual maximum speed for incoming and outgoing transfers between the chip cyclods and microsd ?

Thank you!!!

It depends upon the speed of the MicroSD. A Japanese MicroSD is faster than a Taiwanese MicroSD. A Class 6 MicroSDHC is faster than a Class 4 MicroSDHC. They all have different benchmarks.
