Storage.VirtualDisk.DiskCachePolicy (Read or Write)
Description
Set the physical disk drive caching policy of all members of a Virtual Disk by enabling the Disk Cache Policy.
When this feature is enabled, the physical disk drive writes data to the physical disk drive cache before writing
it to the physical disk drive. Because it is faster to write data to the cache than to a disk, enabling this feature
can improve system performance.
