I’ve often wondered when the DRAM-backed storage revolution was going arrive.
Not long ago, 64GB SSDs were the bare minimum you could get away with, and only the most expensive setups had 64GB RAM. Now we’re seeing 64GB modules for consumer laptops priced reason cheap.
I wonder: if RAM prices head towards $0.05/GB (around $50 for the cheapest 1TB) that we’re currently seeing for SSDs, would that allow the dream of a legitimately useful RAM disk to become a reality?

Become? I strongly doubt it.
You can make a great RAM disk today, but if you don't find that useful enough then the future isn't going to make it much better.
In that future, you don't need a RAM disk for your 800GB compile folders to live in cache or for your zero-loading-screen games to stream data at 50GB/s off your PCIe 7.0 drive.
Big banks and stock traders do that. They just don't organize it like a disk, because what'd be the point?
(And, of course, you want ECC memory for that.)
