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)?

    The idea is that blkdiscard will tell the SSD’s own controller to zero out everything

    Just to be clear, blkdiscard alone does not zero out anything; it just marks blocks as empty. --secure tells compatible drives to additionally wipe the blocks; -z actually zeros out the contents in the blocks like dd does. The difference is that - without the secure or z options - the data is still in the cells.

    always encrypt all of your storage

    Yes! Although, I don’t think hindsight is helpful for OP.
