You dont waste SPACE but your end up with two different stripe sizes across the raid group.
ONE stripe ends at 300G deep, another much shorter stripe goes from 301G deel tp 600G deep on the new drives, in the new RG.
..two different IO performance levels in the same aggregate.
..and thats just a simplistic view of the issue. It can get complicated as the physical aggregate filesystem ages.
Sorry Jeff, I didn't read your post carefully enough.
