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.

Why are 100 GB Blu-rays so much more expensive? (alien.top)

I have recently thought about burning some data to Blu-ray and therefore looked for some cheap blank discs. To my surprise, higher density Blu-rays seem to be much more expensive than lower density ones. In my country (Germany) for example, I could buy a 25 GB BD for 0,44€. A 100 GB BD would cost me 8,77€! At that price, it would be more efficient to store 100 GB on four 25 GB discs instead of one 100 GB disc (1,76€ vs. 8,77€). Sure, if it is one file I would have to split it first and combine it again when I want to access the data, but that effort seems to be worth it.

Why are high capacity Blu-rays so much more expensive, especially compared to HDDs or SSDs where the price per GB/TB usually drops with higher capacity?

Just curious as to why you're looking to store that much data on a high capacity Blu-ray disc (BDXL) as opposed to flash storage, SSD or a hard disk. The medium, as you've come to find out, is expensive and from what I understand you need a specific optical drive to read BDXL media. I know these discs use a non-organic material but I question how resistant it really is to the elements. Disc rot, though not common by any means but much more common than bitrot I feel, is something I'd try to avoid.

depends on location power can be a big issue.

it can be cheaper per year to burn disc , then hdd/ssd storage.
