@nyanotech really shows the massive difference in material cost when they have to meet the full V90 / U3 specs for sustained transfers. so much more fast flash required.

@gsuberland anyway i bought new cards (the middle one here and one of the lexar 2000x, planning to use both of them as the pair in the camera) because i noticed that the cheaper model sandisk i was using before would have a few bits changed every time i copied the files off

@nyanotech ugh that failure mode is the wooooooorst

@gsuberland hopefully having two different brands in the mirror should abate this in the future

the sus part is that this was my first time using those two cards, and they came from a brick and mortar store so probably weren't counterfeit...

@nyanotech this is why making SD cards the defacto storage medium for SBCs was such a huge blunder. they're bitrot hell in failure modes, the cost incentivises fakes, and you can't even guarantee integrity of data on a brand new card even if it is legit. plus they're slow as shit unless you pay the toll to use the full-fat SD protocol.

@gsuberland speaking of fakes, i'm annoyed i had to go to adorama to buy these

@nyanotech not a retailer I've come across before
