Google Drive File Stream is a popular choice for storing user data because it's easy to access to users (i.e. desktop icons with drive mappings) plus user files are not all copied to the user's computer. This saves a lot of space on your drive and almost eliminates sync errors. File Stream is only available for Google Apps G-Suite users.
By default, when using Google File Stream, all users on a server can see each other's Google File Stream Drives, those drive letters are assigned randomly. The reason behind this is Google Drive File Stream is running using the SYSTEM context instead of the USER context. This makes it so that the drives are globally assigned on the whole User Session Server instead of the individual user, as a Shared Drive normally would.
