So, which driver is responsible for passing the trim command all the
way down to the disk?
Also, when BIOS has native ACHI and IDE modes for SATA, is the former
better for the "trim" things to work?
Or, if nothing in Win7 is aware of "trim", is some driver needed from
the SSD vendor? I have not seen anything of this sort for my SSD.
