Seeing these errors means "the SSD is on its way out," according to HTWingNut.

Since we're simply talking about being unpowered for a while, wouldn't a simple full format fix/reset all ECC errors? No need to scrap the drive.

Surely a cap/transistor temporarily losing charge shouldn't permanently destroy it!

Anyways, HDD for 6-24 months offline data storage, SSD for always-online data storage, and flash if you're a masochist like me.

I think tape storage has the best longevity in offline data storage, but it's been a while since I checked.

As we all slowly step back from CD-RW, no quick movements.. or was that all just a bad dream?

https://en.wikipedia.org/wiki/M-DISC

M-DISC's design is intended to provide archival media longevity.[3][4] M-Disc claims that properly stored M-DISC DVD recordings will last up to 1000 years.[5] The M-DISC DVD looks like a standard disc, except it is almost transparent with later DVD and BD-R M-Disks having standard and inkjet printable labels.

In 2022, the NIST Interagency Report NIST IR 8387[25] listed the M-Disc as an acceptable archival format rated for 100+ years, citing the aforementioned 2009 and 2012 tests by the US Department of Defense and French National Laboratory of Metrology and Testing as sources.

That being said, that's 100GB a disc. You can stuff a lot more on a typical hard drive, and I appreciate that people want to easily and inexpensively reliably store very large amounts of data for the long term.

EDIT: At least in a quick search on Amazon, while there are plenty of drives rated for M-DISC, I don't see any kind of "take hundreds of discs, feed them mechanically in and out of a drive" device that'd let one archive very large amounts of data automatically. You'd need 100 of those to fully archive a 10TB hard drive.
