One 10TB drive: drop it once, sneeze on it twice, let mildew kiss it — gone. Ten years if you’re lucky.

SSDs? Sleek courtiers with short memories. Leave them unpowered, and they forget your secrets in a decade or less.

Burned DVDs? Peasant-strong, cheap as barley, and loyal if kept cool and dark. Expect 20–50 years, sometimes more.

One scratches? Toss it. Another cracks? Burn two more. Quantity beats fragility.

Best long-term plan: many cheap discs, spread wide. Redundancy is your shield, not some gilded vault.

Answer plain: burned DVDs last two to five times longer than HDDs or SSDs — and because they cost pennies, you win by making many, not worshipping one.
