    It’s nice to see how the AI ‘hype’ is accelerating (no pun intended) technology like storage…but at what point does processing become the bottleneck and not storage? Is that not already the case?

    Is the latency in flash devices really from the charge trap physics itself? I thought it was more in all the overhead to make sure the bit(s) are actually what it seems like. Also, if there were a market for low latency storage surely Optane wouldn't have died and we'd be living a better, more random read/write performant world.

      Optane was too expensive for not enough of an improvement. It either needs to be as cheap as flash or it needs to be so much faster that people are willing to pay a premium (say, as much faster than an SSD as an SSD was faster than an HDD).

        Optane is still faster for random IO (latency, peak and average) than any pcie5 modern consumer SSD by quite a bit. Some enterprise SSD are about equal but come with equal cost and size constraints.

          And enterprises will pay for that. But it wasn't going to go mass market because the effect to the average consumer wasn't big enough to sell to them.
