I am giving away a shitty 128GB SSD, which was used with LUKS 2 for most of it’s lifetime. As far as I know, it’s good practice to secure-erase it, but I’m too lazy to reinstall the OS on it (I already did it once). Is it really needed?

Ah, fun fact, dd won’t actually cover all the blocks since SSDs have reserve blocks and IIRC they do rotate which ones are in use vs which are not, to even out wear
Yes of course this will only rewrite some number of blocks that total the disks reported capacity. In the case that a person is worried about hidden blocks being preserved by a wear leveling algorithm they could just run the same command again and that would get em all.
