Separate 1TB allocations do not exist since they are in RAID configuration i.e. 2 for E drive and 2 for F drive. In this configuration, they are operating as only 2 separate drive striped pairs for speed.
The 6-core is mounted in a Coolmaster 690 case equipped with an external SATA connection in a top compartment. I presume I can mount an external drive here e.g. a second SSD connected to SATA 6G that may be a good idea for My Docs and the default Scratch discs (Previews/Cache) that appear to be automatically allocated to the Adobe folder under My Documents.
