Physically Immutable Optical Archive Libraries

Savartus optical libraries promise 100-year, EMP-proof data archives

Savartus introduces Enterprise Laser Storage (ELS), a family of optical archive libraries that store data on Blu-ray or Folio discs with physical WORM (write-once-read-many) technology. The systems are immune to EMP, viruses, and malware, and media last 50–100 years without migration. Capacities range from 0.1 PB to 8.3 PB per library, with power consumption under 1 W/TB. They integrate via web interface, CLI, or Glacier-compatible APIs, offering a low-cost, long-term archival solution for compliance and retention.

Optical discs last for a minimum of 50-100 years while other media types will need to be updated or replaced every 7 to 15 years.

    With that modern LLMs are capable of I'n seriously considering investing in at least M-DISC storage or similar to store stuff I don't want to lose :). It's unlikely that both iCloud and Synology get hacked at the same time, but the probability is higher than I could imagine before.

    I’ve always wanted to have a media format as described in Infinite Jest. This is in that neighborhood…

    How does this compare vs Microsoft’s Project Silica? Available for purchase being the immediate differentiator, but curious how they fare technically.
