Storage hardware commonly stays in service for 8–12 years — past End of Sale and into End of Service Life. Without OEM hardware support, security patches and firmware updates stop. Third-party hardware maintenance and extended support can keep 1812-81H and similar hardware operational for another 3–5 years past EOL.
