Datasheet says:
* Enhanced Power-Loss Data Protection with Tantal capacitors

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,
