Topic: Arduino Uno R3 SD card shield reading speed (Read 874 times) previous topic - next topic


Hi everyone,
I am designing an application using arduino uno R3 with SD card shield.
I am going to read binary data from SD card, but I don't know data reading speed from SD card.
Do you guys have any comments about this issue?
Thanks in advance.


fat16lib has posted numerous speed results for his SDfat.h library.
Do some searching, or do your own testing.

Why does it matter? It is what it is.


It's tens of kilobytes per second. How fast do you need? Data faster than that will have to come from FLASH or SRAM.
