Even windows vista thru 10 can do up to 256 MiB of primitive HDD to SSD cluster caching thru Readyboost.
Is optane useful for consumer OS's? Can optane even work with non-server motherboards? It sounds like no is the current answer.
depends on your goal, workloads that demands every scrap of speed you can throw at it can benefit from caching. no idea, i haven't used ZFS as it isn't supported by Windows.
by logic of "realworld workloads", anything faster than your typical SATA SSD isn't really that useful for consumers, even if we disregard the price difference.
to point out, the application load speed difference between the fastest NVMe SSD to an average SATA SSD is only within a few seconds.
where as file transfers is entirely limited by the slowest point on the chain.
e.g. HDD-SSD is bottlenecked by HDD, Internet-SSD is bottlenecked by internet, even gigabit internet is only 128MB/s at best.
this is why i had pointed out before that we're already far beyond practical sequential speeds, its entirely e-peen at this point.
what we actually need is speeding up IO and lowering access latency, specially at the smallest IO requests like random 4K and such.
this *will* speed up applications more than increasing sequential speed by 10times, so yes Optane being used as RAM is what we should be aiming for.
