What is the reason for wanting the quorom drive on a seperate physical drive than the data drive for SQL Server

Is it just so that if SQL would fail, then the quorum & cluster would still be up? If so, then is there really any pressing reason to seperate them if my clustered server is ONLY used for SQL Server

Maybe it would be a little easier to recover

Or is there a pressing performance or stability reason?

First, if there is more than one virtual server on a cluster, the entire
cluster is down if the first instance goes offline.

Second, the quorum drive needs to have little or no contention for writes,
otherwise the cluster can bet badly out of synch and become unstable.

There are more benefits to having the quorum on a separate drive than any
other clustered data, but these two alone should be enough. The entire
point of a cluster is high availability and sharing the quorum with virtual
server instance takes away most of the advantages.
