Running out of space on 4TB My Cloud Home

I’ve had a 4TB My Cloud Home for about 3 months and am already running out of space (3/4 full). I’m using it as a home server, and to backup 4 computers. Is there an upgrade path, add-on product or a any kind of recommendation for when I inevitably run out of space on this HD?


Here’s my suggestion.

Thanks CatOw. That’s a pretty steep price point. $400 for 8TB. I probably only need 6TB but I’ll check it out…
