This read-only enumerated value indicates the type of media used in a long-term storage device, such as hardDisk, floppyDisk, or one of several optical disk types. An administrator uses it to know what kind of physical media a storage entry represents before deciding how to treat capacity or removability expectations for it. For example, seeing clntDiskStorageMedia report floppyDisk on an older client would tell the administrator that device's low capacity is expected given its media type.
