If you could also test the series with zonefs, to hammer it some more that would be good (I unfortunately do not have any zoned UFS devices to run that myself). You can run zonefs test suite (see https://github.com/westerndigitalcorporation/zonefs-tools/tree/master/tests). Simply execute "zonefs-tests.sh /dev/sdX" as root and everything should run (need zonefs-tools and fio installed). > > Thanks, > > Bart. > -- Damien Le Moal Western Digital Research
