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 SSD always worse for long term storage vs HDD? (alien.top)

I have seen that SSD storage needs electricity, in order to not lose data, so: If a Linux system with an UPS, that works as a NAS that runs 24/7 existed, and the data would be only written 1-10 times, the "full" capacity of the each physical drive, so TBW wouldn't be an issue, with, a Raid 1 consisting of 4 drives used for 4k videos, and after a few years for 8k videos, would It be better to use SSDs or HDDs for this purpose with unlimited money and wanting a "no need to modify me for an eternity system"? With equal parts, would the HDDs system be more or less reliable than the SSDs system?

SSDs do not lose data without electricity. This has been debunked as far back as 2015. That said, reasonable safe storage conditions (temperature, moisture, etc.) should be a no brainer. Don't shove them in a box in an outdoor storage building for years and expect good outcomes.

Right, but that chart is OLD and talks nothing of modern processes. SLC, MLC are much less susceptible to loss of data because of only 2 or 4 voltage charge states per cell. Looking at QLC especially with 16 different voltage states per cell, just a small voltage loss would mean data corruption.

This is likely more concerning for well worn SSD's however, and not for a reasonably fresh one.

That article is confusing. They claim you don't need to worry, then they drop a sentence like this.

Even a worn-out SSD would still go a year without data loss, according to the original presentation, and that’s while being stored at 87 degrees Fahreneit the entire time

So which is it? If I have a SSD in a drawer I sure hope it will last more than 1 year.
