Also corroborated at:

    https://www.anandtech.com/show/12448/samsung-begins-mass-production-of-pm1643-sas-ssds-with-3072-tb-capacity

    "Some of the features of the PM1643 that Samsung is willing to
    discuss right now (metadata protection, power loss protection,
    data recovery, end-to-end data protection, encryption, etc.)
    confirm that the drives are indeed aimed at servers that require
    advanced reliability."

Cheers,
Andy
