btw it's not just OS-level filesystems; there's another translation layer between the OS and physical storage (needed for wear balancing etc) and other requirements to make sure flash cells are properly written (https://sabrent.com/blogs/storage/power-loss touches on this). could things be better than they are now? possibly. but what you are doing with killing power during heavy writes is pretty much guaranteed to cause damage, possibly permanent, to your drives.
