I picked up a 2TB 980Pro and installed it into an external USB-C chassis from SSK. I now have extremely fast external storage to edit from on the go without filling my internal system drive with crap media footage. At ~$100, that enough to have one per project and avoids the "which drive" question. It's now, get the ProjectX drive, or get the ProjectY drive. It's the happiest I've been as a mobile editor.
