MD will adjust its speed while initializing, thus the fastest way is to
do nothing on the system, avoiding any other disk IO. This will cause MD
to use max bandwidth.
One thing you can do for testing is to create a smaller array which will
of course initialize faster.
Please run mdadm -E /dev/sdX for all RAID disks before and after reboot
and watch out for differences.
