'bit old'? - if only freebsd-update handled updating to 'stable' (unless it
does?).
Anyway, the camcontrol runs on this ancient 9.1 system ;) and shows:
"
data set management (TRIM) yes
"
So it is supported by the drive - remembering the file system is mounted
from '/dev/raid/r0' - i.e. not the actual underlying drive). But everything
I've seen about geom etc. indicates on this version is should support
'trim' - it may well even be using it, but with the warning logged about
'disk does not confirm that it supports trim' - I'd rather be sure...
