Comment on If I wanted to bury a hard drive for archival purposes (e.g. Country becoming Dictatorship), how to keep the contents from being damaged and where is the safest place to bury it?

  SSD would be 100% dead unless you buried it with a power source.

    Huh? Why? Should SSDs not be able to contain data without power?

      That’s one of the downsides of SSDs, you lose data really fast without power. Like, after a year, your data will almost sure not be intact.

      Flash memory stores data as a voltage level, with different values being a tiny distance apart. The voltage slowly leaks out of the cells and has to be periodically topped off.

      No, they’ll start to corrupt within a year or two. They need to be powered to retain data.

      After 30 years you can forget it.

      Sadly, no.

      There was a recent paper on this. The failure rate was higher than expected. You’ll have to search for it; I didn’t save a link.

        Leave a USB drive in a drawer for a couple of years and you can prove this one at home.

        That’s why my backup drive is an old spinny hard drive.
