Not at the moment. I imagine the Resonessence team could enable this if demand was there. It's an interesting idea, but probably best for people who connect a monitor to their system. Browsing through a 128GB SD card is tricky enough on the OLED display - a 2TB hard drive would take ages.
I use SD cards exclusively on my Invicta and find them quite convenient to use. However I would agree that browsing using the OLED display can be cumbersome in large capacity cards (presently I use only 64GB cards), but have managed to deal with this fairly effectively by creating subfolders. It has been said the 2TB SD cards could in theory be produced, although it's unclear if or when this would actually happen. My greatest concern with using a very high capacity SD-type card (greater than 128GB) would be the possibility of card instability or failure. I've never experienced this with the SD cards I use with my Invicta, however I did have this problem in an DSLR camera. I have been curious about the possibility of using an external hard drive via the USB input on the Invicta/Mirus, and it would be an option that I might want to consider at some point (maybe). Using sub and sub-subdirectories, I think I could fairly easily navigate 1-2TB of files even on the OLED display. I would probably prefer that option over using a very high capacity SD card but presently I really have no problems at all using multiple smaller SD cards.
