I think you'll find that these 3TB, 4KiB physical sector drives are still exporting logical sectors of 512B (this is what Anandtech has indicated, anyway). ZFS assumes that the drives logical sectors are directly mapped to physical sectors, and will create an ashift=9 vdev for the drives. Hence why enthusiasts are making their own zpool binaries with a hardcoded ashift=12 so they can create pools that actually function beyond 20 random writes per second with these drives: http://digitaldj.net/2010/11/03/zfs-zpool-v28-openindiana-b147-4k-drives-and-you/ Cheers,
