HAST (same for Linux DRBD) adds an additional stack between the disks = and ZFS. In addition, HAST may require a lot of network bandwidth depending on = the pool layout, much more than the incoming data throughput. Built-in ZFS replication would require not much network bandwidth than = the incoming data throughput itself.
