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]. Roughly speaking, the idea of
these attacks is to move an SED from one machine to another without cutting
power, i.e., by replugging the data cable only. [...] Some machines are
arguably more vulnerable when using SEDs." Watch the videos... [1]
