--- Comment #14 from Alexander Holler <holler@...oftware.de> ---
The FS doesn't have to give a promise for the storage.

If the storage doesn't overwrite the same blocks (which it did for 25 years and
still does on most conventional HDs) and doesn't offer a way to really get rid
of stuff (like Secure Trim), then the storage can be blamed.

Using encryption is just a workaround. And what makes you believe that the used
encryption is secure? Or that the used encryption is still secure in some
years. Encryption often suffers under bugs in the implementation, bugs in the
algorithm itself and from Moore. Just think at all the "encrypted"
zip-archives. I a few years people might laught about the stuff used today to
encrypt.
