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.

Most efficient and economic way to store about 20 TB of data (alien.top)

Hey gais, pretty much the title. So far I was buying HDDs every few years always having a backup, had some drives fail tho. Today I was visiting a local data centre and they are using these cool but expensive high TBW enterprise TLC SSDs, (Samsung, Micron, Kioxia).

I know shiz about data preservation, if I buy one of those, do you think they are going to last longer without failing? If I lets say give them a power up once a while?

But it's probably still way cheaper to just swap bad sector HDDs.

Depends what you want/need. You could just buy a 20TB disk (or two 10TB disks is probably cheaper). If you want redundancy, get (3) 10+ TB disks in a RAID5 array or raidz1 pool. If you want more redundancy, step up to RAID6 or raidz2.
