However, latency is about both the latency of the arm movement and the rotational latency. The latter you can't overcome by short-stroking.
However, short-stroking does point to an interesting problem when hard drives were still relevant.
If you didn't size your storage right, you ran out of IOPs long before you ran out of capacity.
For instance, if you run VMs on your SAN / storage array, you may have to stop putting VMs on the storage long before capacity is reached.
