alt Hacker NewsTo maximize device performance when wiping a drive to use for something else, I use nvme format with --ses=1.
Which in theory should free all of the blocks on the flash.
Really hard to find good documentation on this stuff. Doesn't help that 95% of internet articles just say "overwrite with zeroes" which is useless advice
Anything that works at the logical block interface will not usefully wipe the device. SES 1 will physically hit every erase block on the device with 20V to blow it away. This happens suspiciously quickly (< 60 seconds typically) but that's just because flash is great.
