I was told absolutely secure disk erasure is actually no longer needed on SSDs due to TRIM.
It however _is_ absolutely necessary for magnetic media (HDD even when supported by SSD, and tape).
But in both cases, if you want to be _absolutely_ sure nobody can read data from a drive after parting with it use Bitlocker (Windows), FileVault (Mac) or LUKS/dm-crypt (Linux/BSD)
