There used to be battery backed ramdisks with SATA interfaces. Are they history now? These days it would be NVMe or whatever, of course.

Radian makes ultracapacitor backed RAM cards with flash backup that appear to be NVMe devices. They do a nice job for things like Write Ahead Logs and ZFS ARC/ZIL. They offer effectively unlimited write durability with a tradeoff of cost and capacity.
