Why are 100 GB Blu-rays so much more expensive?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
BD-RE XL you mean. Sorta. It was/is much more like DVD-RW functionally than DVD-RAM.
DVD-RAM was truly trackless MO. You could format one with any HDD/SSD file system.
BD XL is the best consumer archival media out there. But it's not cheap compared to stashing a few 18TB drives in different locations with a Faraday cage.
