Well it depends if each disk is a physical disk(less likely) or LUN
striped over multiple disks in RAID configuration (external storage,
most likely the case).
If the former is true - it makes sense to stripe the ASM extends over
multiple physical drives for performance.
If these are actually logical units that are already striped over
multiple physical drives, me personaly, I don't see how it could be
beneficial ...
