Hi, I'm experimenting with a 4.1 for use in a logging application and am successfully using the SD library to write to the inbuilt SD card.
Ideally, I would have a second SD card and write to both cards more or less simultaneously to improve reliability. Access speed is not critical.
Is there a way to achieve this?
Thanks in advance for any advice anyone can give on this.
