I am open to writing one and including the inputs everyone is contributing here.
In my search, I also saw some references of alignment issues for partitions.
this is what I used to setup the partitions for the md device

sfdisk /dev/sdb <<EOF
unit: sectors

63,104872257,fd
0,0,0
0,0,0
0,0,0

I've read a recommendation to start the partition on the 1MB mark.
Does this make sense?

I would just make the raw disks members of the RAID array, e.g.
/dev/sdb, /dev/sdc etc and not partition them.
