It's possible that those options have been set in a certain way, for example, to have UFS run with suboptimal settings. I thin dd operates on file system level here (instead of "on bare device"), so those FS settings _might_ have an impact on the results. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
