Right now the best way is download the PG Pak to an external drive, install it selecting C:\bb and X:\RealTracks X:\Drums then you are good to go, no import VAT.
Then at a later date if you find a good priced SSD grab it as they are getting cheaper all the time.
You can just clone the drive, swap it and copy the RealTracks & Drums folders to C:\bb\, then in Prefs set the RT & Drums to the bb folder.
