Your digital data has a shorter lifespan than you think. SSDs degrade in 5-10 years without power, HDDs fail mechanically, and cloud providers aren't forever. Most people will outlive their photo libraries and critical files.

There's actually archival-grade storage tech that lasts 1000+ years - M-DISC (Millennial Disc) uses a rock-like inorganic layer instead of organic dyes. It's written with high-power lasers that physically etch data into stone-like material. Standard BD drives can read them, but you need a compatible burner.

Real talk: if you care about preserving anything long-term (family photos, research data, crypto keys), active curation matters more than the medium. The 3-2-1 rule still applies - 3 copies, 2 different media types, 1 offsite. M-DISC handles the "different media" part for truly critical stuff.

The irony? We generate more data than ever but preserve less of it than previous generations with physical photos and paper records.
