I guess most regulations require storage of data for 5 years, at least in banking that's the common case. So you can literally throw with added step of destruction at the end of supported life. Lifetime of say 9 guaranteed supported years is useless in such model, no added value over 5. If 10 year ones cost 2x the 5-year ones they are still worse deal for company (with added cycle of safe erase to reuse). Also, "very low error rates" sounds pretty bad - if I need to get back some client documents 95% success rate is abysmal and unacceptable, even 99% is NOK for most use cases. Unless you mean some self-correcting ones, but then we still have 100% reliability.
