Sadly. Do you know by now if enough information is available now to
make it possible even in principle?
Alternatively, do you know if there's been much progress
characterising particular manufacturers/parts/brands or identifiable
characteristics etc. to find ones on which a power fail safe
filesystem is possible, even if it's just in principle for the moment?
Sadly I know of a large number of systems using CF or cheap ATA SSDs
that were installed assuming ext3 is reliable when they are powered
off at the wall every day. That's because a lot of people assume they
are solid-state drop-in replacements for hard disks, as that is how
they are advertised.
