Note: The time required for the writing processing of data from the cache to the
external volume (destaging processing) depends on the volume capacity (more
time is required for the larger volume than the smaller one). The processing speed
is about 20 MB/s. However, the processing speed depends on the performance and
the status of the external storage system.
