Nope. The drive's firmware generates the key pseudorandomly when it receives the "securely wipe drive" command, this happens at least once before the drive is shipped from a factory. Thence, the key remains unchanged, unless another "securely wipe drive" command is received. This happens transparently to the user.
- leereeves 9y agoEvery SSD works that way? Is that a standard?
- Piskvorrr 9y agoBog-standard. As mentioned in sibling thread, you could find really old SSDs without this feature, but they're getting rare.
- ericseppanen 9y agoDrives that lack cryptographic scrambling are not rare. Search a few vendors' sites and you'll find some that don't support "self-encrypting" capabilities.
- wtallis 9y agoIt's pretty common for drives to have hardware AES support even if they don't implement the full TCG Opal feature set for use as a "self encrypting drive". I think Phison is the only SSD controller vendor that doesn't advertise encryption capability on all of their mainstream SSD controllers.
- trapperkeeper74 9y agoExactly. Millions of times faster than DBAN.
