Hey guys,
I want to shred/sanitize my SSDs. If it was a normal harddrive I would stick to ShredOS / nwipe, but since SSD’s seem to be a little more complicated, I need your advice.
When reading through some posts in the internet, many people recommend using the software from the manufacturer for sanitizing. Currently I am using the SSD SN850X from Western digital, but I also have a SSD 990 PRO from Samsung. Both manufacturers don’t seem to have a specialized linux-compatible software to perform this kind of action.
How would be your approach to shred your SSD (without physically destroying it)?

SSDs don’t store the data like HDDs, where you’d overwrite the same part on a magnetic platter. The controller on a SSD will instead handle it, do some magic and decide what to do. So if you use
ddto replace some part with zeros, it might instead invalidate the old data, allocate new memory to you and not really overwrite anything. That’s why SSDs have separate commands for wiping content.I’d say google for “ssd secure erase”:
