I am working on a project that requires some data to be logged on a Teensy 3.1. What are some simple options for storing data?
One of my constraints is I cannot spend very much time writing data to a device. So whatever I write to cannot block my application for very long. I read that SD cards can cause the app to block for long periods of time. So I am wary of that option. I read something about "SPI mode" or SDIO mode. Not sure which is which, but people seamed to indicate that SDIO mode is faster. I also thought about using the internal flash on the device, but that would limit me to 256K - minus my apps storage space. Not sure that will be enough.
I am thinking maybe high capacity EEPROM or some other technology. Also, whatever device I use may end up being exposed to 300F for long periods of time (not even sure I can use a Teensy 3.1 at that point). I also realize because of that fact I may end up redesigning multiple times. I know other people will test components actively at various high temps to determine what devices pass and fail under those conditions.
So any thoughts on fast storage methods would be awesome, thanks.
