HDD GURU FORUMS

This is purely an academic question.

An SSD with controller brand X, some NAND-chips brand Y. The drive is fully encrypted by the user (no hardware encryption). Controller X dies because of some reason, but NAND-chips are intact. An exactly the same drive is bought (same X, same Y, same everything) as a donor.

Recovery options (four separate, not consequtive):

1. Chip off.
2. Replace Dead X with Donor X.
3. Move NAND-Y to donor drive (same locations).
4. Fill Donor with some data, perform chip off recovery to get the structure.

Option 1 is out of the deal due to the full drive encryption, but what about 2-4? Are any of these feasible for an encrypted scenario?

Isn't the encryption key tied to the controller in some way?

Let's assume it isn't, just for the sake of an argument.
