I don't wanna be rude, but with you having already maxed out 70TB of capacity, this might be the time to consider moving to a larger storage device that also has active support behind it. The Helios64 always was a low-power hobbyist device which still has problems that probably will not get fixed. A larger device could also net you additional data protection features (hardware raid-controller, ECC-RAM, more CPU for checksums etc.).
