Basically none,

The only one that might be helpfull is the resource aggregation of datastores into a datastore cluster. But this is resource aggregation at its most rudimentary form. When creating a virtual machine and use a datastore cluster as destination, you still need to select the datastore that will store the virtual machine.

Storage DRS disabled =

No initial placement calculation

No space load balancing

No I/O load balancing

No VMDK affinity rules

No maintenance mode

Therefor a datastore cluster without storage DRS enabled is some sort of a datastore folder.
