Yeah I agree about sd card reliability concerns. The funny thing is that I've used as cards as data storage inside gun launched munitions (Howitzers!) And they survived 10,000 G of acceleration, but too many writes is a problem!

I use a mounted usb drive for logging and storage so hopefully that helps the sd card stay fresh.

In the name of countless fellow HNers, tell us more right now!


I'm assuming those were industrial cards? A previous employer would stick them in enclosures next to high power motors for decades at a time without issue. Expensive as hell, but damn were they reliable.


No they were normal off the shelf cards, but they were soldered directly on to the PCB and everything was vacuum potted.
