I have 5 new disks and I want to build a raid5.

I am think which one is the better method.

1) build normally, so raid will do reconstruction and i probably want to
wait till it ends

2) zero all disks using dd. then build a raid without need to computer
checksum at all since 0xor0=3D0.=20

in fact, i am thinking which mdadm command can allow me to do (2)
