  • Is there a benefit from this over the inbuilt Secure Erase functionality in most SSDs/NVMEs? To my knowledge, it instantly dumps the current from all cells, emptying the data on it.

    Furthermore, another issue with SSDs/NVMEs is that it automatically excludes bad blocks, meaning that classic read/write operations can’t even reach those blocks anyways. Theoretically that feature could also be used against you to preserve the data on the disk by marking all blocks as bad, rendering them as inaccessible by the file system.

    Of course there’s also the issue of Secure Erase not being implemented properly in some drives, leading to the bad blocks not being touched by the hardware chip during that procedure.
