Huh, not even #backblaze has a very good #solution for #erasing an #ssd https://www.backblaze.com/blog/how-to-wi.. They recommend to #encrypt your data, but it's entirely possible your #ssh key or #password is still #unencrypted on a reallocated block. I proposed about 6 years ago to write a wiping tool but nobody took me up on it... You can use #smart data to predict wiping coverage, etc.
I always like to see the #backblaze #harddrive #stats on #failures https://www.backblaze.com/blog/backblaze.. This is a massive credit to the #computing #community - excellent work.
