@funkylab Honestly you come across as condescending with your posts. Please don't.- Trimming, voltage drift scrubbing, and wear leveling will cause data to constantly get re-written.- While Single Level Cell NAND can hold your data for a decade, QLC can lose data within 1-2 years when left unpowered.- Controllers are aware of this and can counter this if they're powered.Example sources:- https://www.xda-developers.com/your-unpowered-ssd-is-slowly-losing-your-data/- https://www.seagate.com/files/staticfiles/docs/pdf/whitepaper/tp618-ssd-tech-paper-us.pdf SSDs are leaky capacitors.@raymaccarthy @djlink
