    So I came upon this and it's pretty interesting.

    http://www.bit-tech.net/hardware/apple/2010/07/01/mac-ssd-performance-trim-in-osx/1


    They tested the performance of clean ssd's and "dirty" (loaded full of files) on Windows 7 and osx and the osx system had only 2.3MB/s read/write degradation, while windows 7 had drastic performance loss.


    Pretty interesting read if you have time. It's almost as if TRIM isn't needed.

    theres the problem.
    the zero out data writes one large file to the drive.
    thus degrading the drive to its worts state, meaning it cant get any worse.

    No they didn't test clean vs dirty, they think they did. Unfortunately they have to redo their homework regarding ssd's and clearing the ssd. What they actually did was comparing a dirty ssd with a dirty ssd which obviously does not show much of a difference. If they were indeed comparing a clean and a dirty ssd the difference would be bigger.

    The information in that article is incorrect due to a big lack of knowledge on their part so ignore it completely! Other tests already showed the performance degradation and the need for something like trim and/or garbage collection.
