Researchers found vulnerabilities of self-encrypted SSDs. From the abstract: "Self-encrypting drives (SEDs), such as Intel's SSD 320 and 520 series, are widely believed to be a fast and secure alternative to software-based solutions like TrueCrypt and BitLocker. [...] In this sense, hardware-based full disk encryption (FDE) is as insecure as software-based FDE. We also show that (2) there exists a new class of attacks that is specific to hardware-based FDE [Full Disk Encryption].
