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.
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.
