A place to politely discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Yes. All flash memory eventually goes bad, Those little switches can only be flipped from 1 to 0 and 0 to 1 so many millions of times. They can also only be read so many millions of times even if you don't change the bits.
When I have to setup digital signage that plays back off of SD cards we start by getting high endurance cards, and then if you have say a looping video. You don't just put the video on there and loop it. You put several copies of the video and you have it play copy 1, then 2, then 3... then loop to the beginning of the list because then it spreads those reads out over the whole card and it lasts longer before it crashes.
As soon as you have errors with a card replace it. Depending on how heavy you use the card start putting retirement dates on them for some that might be every 6 months, for some that might be every year or two. They are cheap just get rid of it before it goes bad, always have spares.
