  • On big flash memory you typically have more memory on the chips, than ia presented to the OS. Flash has significantly less write cycles, before the block breaks, so the controller monitors the health and won’t use it anymore when it will soon fail. Instead it uses a block from its unused extra space. (Details might be different, I’m not sure about that). This way the lifetime of the SSD is significantly improved. SD cards do the same, I think.

    So the data in the retired blocks will remain and cannot be overwritten by the OS. If they are encrypted and the keys deleted, that won’t matter




  • Honest question: Is there a good comprehensive easy to follow source for reading/listening/watching up on the theory?

    At some point some user linked to a long reading list, where I stopped frustrated after 2 hours of reading and still being non the wiser. In all that time there must be some resource, that is more engaging and especially talking about modern life, not the life in the times of Marx (yeah, I know that the fundamental principles are the same). I’m also ok with multiple hour youtube videos, as long as there are skillfully made and engaging.
