Have tried everything from this wiki but no matter what I do I am not
able to have it aligned 4k.

filebench given this stats (a mirrored vdev):
150541 ops, 2492.698 ops/s, (226/453 r/w),  59.4mb/s,    898us cpu/op,
71.1ms latency

Another mirrored vdev consisting of 512B disks gives this stats:
1684377 ops, 27581.072 ops/s, (2508/5016 r/w), 668.3mb/s,
249us cpu/op, 	 3.9ms latency

Both vdevs are connect via an LSI 1068E HBA
