I’m more about reliability and convenience so running a similar setup (64tb raid 10) but in a NAS as I need the convenience of file sharing + running untethered most of the time.
Thinking about this a bit more I think you won’t see much performance upside over TB3 switching to SSDs from fast HDs in a raid 10 setup (edit: because I assume you’re sequentially writing, large files?)
If you’ve got money to spend and just want speed at all costs then perhaps look at a pcie to dual m,2/Nvie adapter and put both drives in raid 0. You’ll eat a slot but if you’ve already got a 3090 then I don’t imagine you’ll need that second GPU slot. The issue for me is that any kind of solid state drive is never going to last as long or be as reliable as an enterprise grade HD. So if it were me I’d be looking to upgrade the DAS to a TB3/TB4 enclosure and sticking with your existing HDs, assuming they’re fast enough. Maybe you can find one with m.2 cache. And only then spend any spare cash on internal drives.
