> Majority of hard disk encryption done in the HDD/SSD controller is 100 times more crap than BitLocker itself. It's littered with bugs and security vulns. Anybody using it is insane.

Oversimplified and not accurate. Some manufacturers had flawed implementations, others did not. Also, that was a long time ago. There are advantages to hardware encryption. It preserves performance and mitigates other vectors like cold-boot attacks without having to encrypt RAM, which also comes with a performance penalty. By the way, both software and hardware-based encryption can be combined. Cryptsetup on Linux actually offers this, and before you ask, the keys are split. If one is compromised, the other remains secure.
