Call me crazy, (“you’re crazy!”) but I still zero all storage before destruction, sale or repurposing. Belt and suspenders.

- johncolanduoni 1y agoFor SSDs that doesn’t actually guarantee deletion - there could still be some over-provisioned erase blocks that have the old data due to wear leveling.
- jshier 1y agoApple's SSDs are all encrypted at the controller nowadays. No need to rewrite, just reformat and it cycles the key, leaving any recoverable data irrevocably encrypted (until we break modern encryption).
- burnerthrow008 1y agoI thought all SSDs did that for wear-leveling purposes.
- johncolanduoni 1y agoThey do, but consumer ones usually don't implement the additional API (TCG Opal) that lets you lock/unlock the hardware encryption key. Without that capability you can't use it to implement full-disk encryption. They do usually implement the NVMe secure erase feature though, which will rotate it.
- wpm 1y agoI mean, if you regularly deal with data worth the effort necessary to recover, that isn’t crazy at all
- adastra22 1y agoOn a modern SSD it is cargo culting though. Every write is assigned to a new sector. Makes sense when wiping the whole drive though.
