an SD card in foam in a thick metal sphere, like a bowling ball, would survive this, could be used as a backup to the main one.

How do you write to the sdcard while its packed in its foam helmet? If you put a little computer in there then it would have more mass and metal to smash around on impact. Maybe like a tiny usb card reader and a long data cable?

I wonder if running the data cable through the foam would cause problems like letting fire/fuel/water through the helmet and disolve/melt the plastics or if you whip a cable hard enough it can cut right through things like a weed wacker.

there are tiny chip size wireless receivers for small distances like this, you would need some sort of window through the metal, or a tiny antenna inserted through the ball shell and the wireless covers just the inside

or just ultra-thin wires connecting the memory to the outside. the ultra-thin wire will just snap and it's too light to cause damage by whipping around

the big problem is kinetic impact, fire/fuel/water would be easy to solve, for example fire requires oxygen which will have difficulties getting inside through a tiny hole, and I'm sure there is some metal alloy which doesn't melt in typical plane fuel fire temperatures
