btrfs on linux, zfs on pretty much everything, and apfs on apple (CoW filesystems) already append new data blocks to the end of the drive rather than modify existing ones. obviously if this is gonna become a thing they would need to do it with the metadata too. the problem with that is the longer the drive is in use, the more metadata you have to read in to use it. probably easier to use a traditional drive just for the metadata.

besides that, cd/dvd/blu-ray filesystems are all adapted for write-once media. actually, they're purpose-built for pretty much this exact thing (besides the size of the disks they support). so never mind all that other shit i just said
