Oh, that's an interesting article by Unangst. If TRIM would be implemented someday, one thing that would be neat would be that crypto and other softraid would propagate the TRIM. That would be a nice combination between wear level resiliency and disk data safety. AFAIK some other disk crypto solutions do that. The feature comes under names such as "encrypt used space only".
