FYI, be aware there appears to be a queued TRIM bug with the M500 where it may be causing silent data corruption. I wouldn't use discard on this, or any, SSD, in production until it's been well tested.
Until the industry gets its act together on TRIM, I think we're probably better off executing fstrim once a week with a cron job at a time the computer is likely to be idle.
