HDD prices have surged significantly in recent days, and HM-SMR can provide storage with a lower budget. Although it is well-known that SMR has poor write performance, for media files (such as movies, TV series, and music) that are written once, read multiple times, and rarely modified, HM-SMR is suitable. Currently, the built-in BTRFS in Unraid seems to already support zoned devices, but the kernel options have not enabled the corresponding flags. So, is it possible to support HM-SMR on a BTRFS pool, providing a new option for media file storage where redundancy is less concerned? (And I know of course that HM-SMR is not ready for Unraid array mode as that has random writes.)
