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?

cat /dev/urandom > /dev/your-diskshould do it in your case. And in 99% of cases.this is just gonna cause useless wear on the ssd. only do this to hdds
I think you mean doing that for more than once has no extra effect on an SSD. Shouldn’t we overwrite the unencrypted content for at least once?
nope, i mean that’s just useless. (it does kinda do the job, but wears it down, and not as effective since SSDs aren’t really predictable because of wear leveling stuff and lie to the OS) there’s an ATA Secure Erase feature that can be used instead.

Wait, HDDs retain data after deletion? I thought only SSDs did that.
nope its just how the file system works, same on hdd. in fact recovery programs like testdisk/recuva usually work better on hdds because ssds have trim and garbage collection running periodically
