As a FOH engineer, I think you over-estimate the "noise" such a minor
piece of a recording system as the solid-state flash makes. Although
I have heard some hiss from solid-state devices, the vast majority of
their emissions and (and major harmonics) are well above 22kHz.

I sincerly doubt a change of microSD card would have cured your
obvious grounding issues. Noise is great for entropy and poor for
recording, but as a [hopefully] fellow professional, I again think
you're overestimating how much audible noise reduction one would get
by replacing a normal microSD with this particular one. That said,
your depseration that day was likely (regrettably) the precise market
this product is aimed at.
