Resilvering on ZFS in not linear, it is quite some random IO. A ST8000DM004 is capable of linear reads above 200MB/s, and a normal drive should be able to handle the same speeds with linear writes. I would not recommend those drives for use with ZFS from my own experience: one of my drives disappeared after 1.5TB of writes while moving a dataset, and only went online again (with a SMART failure) after a power cycle.
