If the disk has built in encryption, so the storage controller on the disk handles the encrypt/decrypt cycle but presents as an unencrypted disk for all intents and purposes to the user. All thats needed to wipe the disk is to delete the encryption keys. Its a pretty common feature in enterprise disks and i quite like it. Saves a lot of time when decom time rolls arround
You don’t need to encrypt empty disk space. Formatting a disk only writes some data structures here and there, leaving vast majority of the disk unchanged.

You are jumping to a point in time after what I am asking:
“all you need” is to delete a key -> No, you need to encrypt the disk before, which is the step prior, and without it, deleting a key change a thing…
So basically, the part “hardware” built-in could make sense, but the guy didn’t specify any if this…
In other words, zeroing the disk is going to be faster “in normal circumstances”.
