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.
