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.

Two 20 GB drives in RAID-1 with a 3rd 20 GB drive as off-site backup will give you a pretty good level of data security.

It’s not 3-2-1, but it’s a lot better than just a single 20 GB drive. :)
