BTRFS can handle zoned disks. The doc claims that it was a natural fit with the way BTRFS works.

The problem is that you cannot buy host managed zoned disks.




WD was pushing for this standard a few years back: https://www.westerndigital.com/company/innovation/zoned-stor... I'm not sure what happened to it / whether it was successful or not.


I think they also sold HA-SMR (host aware SMR, a mix of drive managed and host managed) drives to datacenters but I couldn't find any recent news so I guess those aren't that common.
