My experience at Alacritech was that Trim was so expensive timewise that it could not be used in that application space. Instead, SECURITY ERASE on the relatively infrequent reboots cleaned things up pretty well. This should be with a grain of salt because I expect trim timings are not only vendor dependent but firmware release dependent.
