What is the make and model of your computer? BIOS or UEFI?
What is the make and model of your SMR drive?
What partition scheme do you use -- MBR or GPT?
How do you intend to use the partitions -- e.g. boot, swap, root, usr,
var, home, data, online backup, offline backup, archives, images,
sneakernet, other?
STFW "zfs smr disk drive":
* I see several reasonably current articles that advise against using
ZFS with SMR drives; notably the Western Digital Red with SMR:
https://www.truenas.com/community/threads/update-wd-red-smr-drive-compatibility-with-zfs.88413/
https://arstechnica.com/gadgets/2020/06/western-digitals-smr-disks-arent-great-but-theyre-not-garbage/
* I see a 2014 OpenZFS conference paper regarding host-aware SMR. I do
not know if this technology made it into OpenZFS, or if Debian includes it:
https://openzfs.org/w/images/2/2a/Host-Aware_SMR-Tim_Feldman.pdf
STFW "btrfs smr disk drive", nothing stands out.
One option would be to benchmark all three choices (ext4, btrfs, zfs).
Make sure to cover all the use-cases, including disaster recovery.
Another option would be to replace the disk with a CMR disk (e.g.
refund, exchange, sale).
