with fast clone in the mix, i would think the ratio of storage consumption for mcs to pvs is impacted more so by the number of datastores you have MCS provisioning into

 

PVS is simple - there is a write-cache per VM and that's about it

 

MCS has the initial snapshot, a rollback instance, any "not yet updated instances" + any "not yet cleaned" stuff + (MCSIO cache if in use per VM) - that is then replicated across all datastores that MCS uses - so the different can be significant
