YouTuber SSD tests reveals problems all round on two-year-old TLC drives.

    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.

        Yeah I believe tape is still king there. LTO is working on some 500+ TB tape for the future IIRC.

          The upfront cost of tape is excessive though. It wasn’t always like that. And LTO-9 missed its capacity target: it’s 18TB (1.5x LTO-8) instead of 24TB as planned. Who knows what will happen later in the roadmap.

        Strictly speaking, I think paper beats magnetic tape on longevity.

        Unfortunately, it loses on data density.

            I was excluding media that are impractical for most people to use.

              Paper would fall under that these days, wouldn’t it? You can’t just fit a word (8 bytes) onto a punch card like the old days, and you’d need billions of the things go even start matching up to modern storage.

                I did call out data density in my first comment. Did you somehow miss that? Not all things that need storing are megabytes in size, though.

                Why would you assume that paper means punch cards? Printers can store far more than a machine word on a page, are relatively cheap, and are widely available. For some things, this can be superior to both magnetic and flash storage.

        Tape presents its own share of problems. If not strored in some very particular conditions, like temp, humidity, and others that I can’t recall, they can stick to tbe adjacent layers, become brittle, curved, etc…

      I actually just pulled some files off of one from 2004-ish. No issues. Found another one from 2008 about a year ago that had no issues as well. Not sure why… maybe because they were so much lower capacity? Like, one was 64MB and that was huge back then.

        They were slc, so the charge ratio was much higher.

        Mlc/tlc/qlc drives have to measure a current very precisely, up to 16 values of discrimination, any charge degredation doesn’t change a 1 to a 0, but a 3 to a 2 to a 1 and given enough time, a zero.

        Also smaller gate dielectric so more leakage.
