Command Line MagicApr 23, 2023
I made these diagrams to generally explain to a college class how file storage layers work on a drive and now when you delete/format the filesystem the file data remains. I couldn't find one online, so made one. What do you think? Any significant issues?

The physical SSD itself does some magic that the operating system may not have access to. I think it does its own wear leveling and manages extra storage that is not even known to the system (overprovisioning). It also may encrypt data itself (a thing that is often implemented badly).
