Recordable CDs Were Supposed to Preserve Our Data Forever, but They're a Ticking Time Bomb
How-To Geek, Tuesday, June 23rd, 2026
CD-Rs promised permanent storage but degrade and hold little data, making them poor long-term archives.
Recordable CDs were promoted as durable, near-permanent storage holding around 700MB per disc, but they have proven unreliable for archival use.
Failure modes include corroding silver reflective layers, degrading dyes, and disc rot driven by humidity and light exposure.
A 50-disc spindle holds only about 35GB, comparable to a cheap USB stick.
Gold-layer discs last longer, but modern cloud, USB, and external drive options are far more reliable and practical.
