At plumbers it came out during the filesystem talk that the discard
option is a really bad idea. It apparently has performance and
reliabilty problems. Apparently, you're just supposed to run a
command manually (that I don't remember of hand) when your disk starts
to fill up.
Yeah this depends on the drive though (on my Samsung drive it does not
seem to have a noticeable performance hit).
The tool that can be run from time to time is the "wiper.sh" script
found in the hdparm tarball.
