But now I hear that the level of sophistication of this varies. Namely, while SSDs, meant for running OS installations and active user filesystems, put the most effort into prolonging their lives, SD cards and USB sticks do not. So it makes sense to use some more flash-aware filesystem on the latter devices, to help reduce the wear on them as well. Looking at the Wikipedia list <https://en.wikipedia.org/wiki/Flash_file_system>, it seems like F2FS is the best bet. Anybody tried this sort of thing?
