    It seems to me the fundamental problem is that the flash-drive firmware is
    trying to do too much: it is implementing, in effect, an additional,
    partial, filesystem layer underneath the conventional filesystem as handled
    by the OS. This additional layer is a log-structured filesystem
    <http://lwn.net/Articles/353411/>.

    Not only is this adding extra complexity and hence unreliability, hacks like
    the TRIM command seem poorly specified and poorly implemented.

    The only real way forward is to abandon all this complicated firmware and
    simply directly expose the raw flash layer to the OS driver. Let the OS take
    care of implementing a purpose-built filesystem that integrates wear-
    levelling directly in its design. A lot of work has already been done on
    this; why not take advantage of that?
