It's much better in latency too[1]. I also wonder if the current products are bottlenecked by the controller and whether DIMMs will see vastly superior perform

  > I also wonder if the current products are bottlenecked by the controller There's no question that they are. NVMe drive prototypes that use DRAM as their backing memory instead of flash or some other persistent memory have about the same overall latency as Optane SSDs. With NVMe, the storage industry is in a much better position to take advantage of 3D XPoint than if we were all still using SATA or SAS, but it's still on a peripheral bus not a memory bus.
