I have a Roon Nucleus+ with 2TB internal drive and 3TB ext drive connected directly to it.
The Nucleus+ is connected directly via USB to a Bryston BDA-3 DAC. Simple and clean and to my ears sounds great. Have a few TB of DSD on the ext drive which is really exceptional. OP, As in all cases it may not fit your ideas or your system plans.
