Datasheet says: * Enhanced Power-Loss Data Protection with Tantal capacitors https://www.hyperscalers.com/image/catalog/!Petar/PM1643%202.5%20SAS%20SSD%20Datasheet_v1.0_for%20General%20(002).pdf 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."
