Anandtech published SanDisk X300s (512GB)
A quote from the article:
Back in May SanDisk announced the X300s, which is the company's first SED (Self-Encrypting Drive). The X300s is based on the same Marvell platform as SanDisk's client drives but with the differentiation that the X300s is the only drive that supports encryption via TCG Opal and IEEE-1667 (eDrive) standards. Due to the encryption support the X300s is positioned as a business product since the main markets for encrypted drives are corporations and governments that handle sensitive and confidential data on a daily basis. SanDisk includes Wave's EMBASSY Security Center with every purchase of X300s, which allows Opal encryption on systems that are not eDrive compatible.
