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.

How did your drives fail? Did you ever just try to save them? Or just toss em?

For 20 TB of computer measured storage you need a 22 TB hdd. ( Due to the way hard drive manufactures market vs how computers read disk size, they use different base systems)

I recently got 20 TB Seagate EXOs for $260 on eBay sold new by Newegg .(20 TB EXOs has 18 TB usable as read by Windows and Linux )

This is TiB vs TB. Base 2 vs base 10.

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. :)

That moment when you realise they said "TV" and you're thinking in GB. You became old today.

Lol, I became old a looong time ago. Back in my day, drives were measured in MB, and we liked it! shakes cane

Where do I find 20GB drives? 🤔

[–] Jon_TWR@alien.top 1 points 11 months ago
