Bounght a 4Tb usb3 backup drive that contains an SMR baracuda - took
quite a few days to transfer the 2Tb from its predecessor. Backup
(Borgbackup on btrfs) is quite fast with small changes between backup
sets - miserably slow otherwise.  I am still in two minds if SMR is
usable (i.e., will finish before the next run is due!) in my scenario.
