Part of why I run full disk encryption is to not worry about that. Don't 
destroy the disk, just destroy the encryption key.

If I did Bcache with an SSD, maybe I could stack it under the 
encryption.  I think the sequential vs. random access patterns are still 
visible at that level.  Heck, Bcache stands for block layer cache.  That 
stacking would work.
