What it concludes

Blu-ray discs are by far the cheapest option available for storage, cheaper by a factor of nearly 2 and 3x over hard drives and SSDs.
Blu-ray discs are the only medium that can touch optical in value besides linear tape open format.
Blu-rays are not appropriate for hot data that needs to be accessed with reasonable frequency or at high speed.
Blu-ray discs can last anywhere between 5 to 50 years depending on quality and materials, and M-disc Blu-rays can last over 100 years.
Blu-rays are ideal for project-based workflows and archiving sensitive files that you do not want online.
For massive archiving projects, the value of tape is impossible to ignore, with tape getting more advanced and Blu-ray prices going up.
