If you install the google stream drive, you can run into some problem regarding drive lettes, it will shift randomly after a reboot, or it will use a drive letter you have reserved for network drive.
You can mitigate this by adding this registry key.
Save as a gdrive.reg and doubleclick. Remember to edit DefaultMountPoint, according to your likings.
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Google\DriveFS] "DefaultMountPoint"="X"
