I agree,
and someone maybe even cares to use the expensive flashs to keep the data
secure, because in some cases the data is more valuable then the drive, but
there are not so much data for use a RAID or something, it's like using a
cannon to kill a mosquito.
I'm telling this from expirience, since I'm currently developing a filesystem
for such a purpose, with minimising writes and aligning them to the pages of
the media + supporting small transactions across files (via ioctl hints by
the app) + usual journalling.
