I'm guessing that the software raid your using doesn't support TRIM then
So the question has to change to 'Does GEOM GRAID support, or allow TRIM' :)
Have you considered switching to ZFS based install, which does support
TRIM in 9.2, 9/stable and 8/stable?
These are MySQL hosts - until we've got some experience running MySQL on
top of ZFS we'll stick with UFS for now - nice idea though (and we already
have other boxes using ZFS).
gmirror may be another alternative that may correctly work with TRIM.
For reference correctly setup MySQL performance on ZFS works well for
use. Of particular interest is some of our data is highly compressible
making ZFS compression of particular benefit for our work load.
