Don't think anybody makes a laptop with 4 NVMe slots. Not saying I need it, but if somebody does there are quad m.2 TB3 enclosures.
IMO you'd be better off backing up on HDDs, you can get triple or quadruple redudancy even at 7200rpm at T5's cost per GB, and HDDs are ofc more reliable too. I check SMART output regularly and never had a single failure w/o enough warning that I couldn't get nearly all the data safely off the disk. The downside is you'll be rolling in big clunky drives, especially if you just use internal drives and stick them into a plug-like enclosure like me

Re: quad M.2 via TB3, that's really only best buy if you specifically need to access like 16TB+ of data at mid-NVMe speeds. The problem is with speed - the TB3 port is limited to only PCIe 3x4, and we've already got 4x4 drives and PCIe gen 5 is coming out next year. RAID won't pay off

A better buy would be an internal card, like this, that's where you can make speed gains, since you're not limited by external ports, which all (TB & USB) have effectively slow controllers.

TB3/4's and USB4's 40 Gbps (with overhead) looks impressive on the face of it, but even mid-range NVMe drives will be getting bottlenecked hard at that speed in 2-3 years time.
