Jim Bell's comment:
I wonder if DRAM-based SSD's would be practical for Chia mining. There shouldn't be a need for non-volatility. SD- cards get a lot of their density by constructing them in many layers, up to 144 I recently read.
I haven't been keeping up with DRAM construction techniques, but I wonder if DRAMs can be multi-layered in a similar way.
