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.
