Even the 100MB/sec won’t work for long as these stupidly small MicroSDs tend to heat up A LOT and then go into throttling where the transfer rate goes down to <1MB/sec.

That and anecdotally, these high capacity SD cards seem to quickly reach the temperature of the sun during any kind of sustained large file transfer

I'd say it's perfect for security cams or any cams using compression. You could store 14 days of 5120x3200, 60 fps, H.256 HEVC video. Or ~1 day of that at 850 fps.

For a brief moment in my life I worked as data manager in a movie set, and remember studying for that job and having to talk with the DP and the cameraman about memory cards, recorders and checking with them that the quality output of the camera were not bigger that the speed capacity of the memory cards. It was fun times, and sometimes I wonder how my life would be now if I never left Argentina and had accepted the next gig the movie producer called me for.

Tiger Direct had a 1GB card in 2002 and it was $900. Blew my money in a 128MB card and lost it. Heart broken.

I remember bringing a 64M USB drive to school and telling the librarians that "this is the future"

I think back then you needed to install drivers, so I was trying to get them to install drivers on all the library computers so that it would "just work" for students. Before then we used to have to burn files onto CDs or DVDs to bring them to school.

Hopefully the lifespan scales with the amount of writable space. Would be even cooler if that factor was improving over time. Any studies or articles on the topic?

Your stepdad?

Up the peehole. Just be sure to sterilize it first.

That does make me wonder how sd cards and ssd compare in terms of volume/tbw endurance. Does silicon have a typical lifespan per volume?
