The Inner Workings Of SSDs

Found a most interesting article series about how SSD internally work: http://codecapsule.com/2014/02/12/coding-for-ssds-part-1-introduction-and-table-of-contents/

It goes quite deep, e.g. explains the internal structure of FLASH memory as well as how the Flash-Translation-Layer (FTL) works. I have not see any such detailed description yet.

hdparm works well doe SCSI disks (or disks which behave like SCSI disks), but it does not work with NVME disks. But nvme does. See here: https://tinyapps.org/docs/nvme-sanitize.html how to erase NVME SSDs.
