What’s the density difference and lifespan between dual layer Blu-Ray (50 GB) and the latest tape standard (multiple TB)? On the surface, I’d think tape is denser and lasts longer. Not to mention that tape is reusable.

Lto9 tapes can store 18TB and are about 231cm^3. BDXL can store 128GB and are about 54cm^3. Tape about 79GB/cm^3 vs Bluray 2.3GB/cm^3.

Denser storages have worse longevity. CDs (and similar) have been found to have the best longevity of the commonly used storage media.
