It depends on whether you are running on a z15 or not, and if not, the values in effect for the DEFMINREQSIZE and INFMINREQSIZE. Check out IQPPRMxx in the Inititialization and Tuning Reference.

IMHO it is matter of Data Class and ACS. I don't consider ADRDSSU dump files which can be compressed or copies of existing compressed datasets.
