How does PVS use less storage than MCS?

Hello,

I keep seeing that PVS uses less storage than MCS and I can't figure out how. If one uses MCS with fast clones non persistent desktops, wouldn't it in theory consume as much space as PVS provisioned desktops?

Thanks in advance

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
