Microcontrollers / Re: SD Card reliability in SPI mode
« Last post by betocool on Today at 02:21:30 am »Thanks for all your answers.
Looks like I can address a few things.
For this project, space is a premium, so additional memory is out of the question. I might consider a NAND flash but I've been down that road before in the past with less than stellar results too. That also requires major hardware changes and yes, time is also a premium!
The SD Cards I'm using, or tested really, are Verbatim brand, they are the most common here in OZ, 32GB. I tried the "Extreme" with a gray stripe, that seems to fare worst. I also tried the one with a golden stripe, that one performs better, but we've still had issues. I will later try out one of the Endurance series (I don't recall the name 100%, don't have the hardware with me) which are completely white, we'll see how that goes.
I will try synching less often, that might help, and I will also wait until there is really no data going on for a few hundreds of ms before turning the card off. As usual all these things take some time to implement but much longer time to test. We'll see.
I appreciate all your comments.
Cheers,
Alberto
