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.

Is a 20 disk raidz3 really a bad idea, for media archiving use cases? (alien.top)

I am archiving a vast amount of media files that are rarely accessed. I'm writing large sequential files, at peaks of about 100MB/s.

I want to maximise storage space primarily; I have 20x 18TB HDDs.

I've been told that large (e.g. 20 disk) vdevs are bad because resilvers will take a very long time, which creates higher risk of pool failure. How bad of an idea is this?

It's way more likely to ruin the files by accidental deletion, destructive commands, software errors, massive hardware failure like your power supply failing and destroying all your drives at the same time or your house burning down.

Yes. This is important and shouldn't be overlooked.
