1TB would be nice, but never heard of these, and the quoted wikipedia page lists:
Like HD DVD, CBHD discs have a capacity of 15 GB single-layer and 30GB dual-layer and can utilize existing DVD production lines.
So sounds relatively equivalent to bluray, which is way to small to backup modern HDD's (10TB+)
- lyu07282 2y agoit's actually 128GB per disk (BDXL), I only know of Chinese companies announcements of 500GB optical disks last year[1], not sure if they are already deployed to some enterprise partners, it's entirely possible. Their more theoretical research goes far beyond that. [2] There are archival storage machines similar to tape drive robots for archival storage in the Chinese market where you have hundreds of such disks in a single unit and 1PB+ per rack.
