Genuinely curious: What would such an alternative provide to the market? Would it be cheaper, last longer, be some medium that offered different performance/longevity characteristics? There is flash storage which provides some tradeoffs with price (especially now!) and performance. Spinning disks seem to be in a sweet spot of relatively cheap adequately performant with an acceptable lifetime/failure rate for a lot of needs... What market need is missing? (Again - not trying to debate, I am genuinely curious as I am not in the storage industry at all.)
