Medium: Speed of initial copy activity is faster than Low and slower than High.

To specify Medium, ensure that the amount of update I/Os (that is, write requests from
hosts to primary data volumes) is 10 MB/s or less per parity group. If it exceeds 10 MB/s,
data volume pairs might become split (suspended).

High: Speed of initial copy activity is faster than Low and Medium.

To specify High, ensure that update I/Os (that is, write requests from hosts to primary
data volumes) do not occur. If update I/Os occur, data volume pairs might become split
