You might consider then getting four 40gbps nVME enclosures, and then RAIDing multiple together (e.g. in a big stripe, you could get 160gbps throughput, only limited by # physical interfaces). Each slice could be +TBs.

Obviously increases your failure rate, but if you're constantly updating the same models (and not creating your own) you don't really need redundancy.
