After about four years, the flash memory can become unstable due to low voltage 
retention.  Also, rememember that flash memory of any type has a finite number 
of R/W cycles.  Using any type of flash memory for long-term storage is a bad 
idea.  I'd put it on something more permanent such as CD/DVD though all media 
types are subject to failures of different type.

You're on-topic here.  I know the moderator.

Later,
