I’m just now seeing your message, wow, thank you so much for your incredibly helpful and insightful reply @Bushmills! The network mount sounds appealing, but I imagine that a power outage or some sort of network interference could take out a print if I’m not mistaken 
.
I’ve decided to go with the eMMC Flash module, and just found this video from Sovol on how to swap it out. Also just ordered the 32GB eMMC flash module (for some reason I thought that there was a MicroSD card mount on the motherboard, but it doesn’t look like that’s the case).
I have a 128GB USB drive, which I’d love to use as well if it makes sense to run that directly on my printer, but am quite clueless on how to mount it/prepare the files but am more than willing to learn 
, thank you again for taking the time to reply and share such helpful advice. Please let me know if there’s anything that I can do to repay your kindness
