Cool, thanks for sharing.

It's interesting that even the drives themselves use this strategy to "erase" data; it doesn't actually overwrite the cells, it just always encrypts all data that goes to cells and rotates the key when it's asked to erase. This strategy is clearly superior, it doesn't cost any wear on the cells to perform, and it's instant.

The multiple locking ranges is pretty neat, I'd never heard of that.
