Intel has been teasing their Alder Stream second-generation Optane SSDs since last fall, with promises of off-the-charts performance increases. They've confirmed that Alder Stream will be using second-generation 3D XPoint memory, which moves from two to four layers ("decks" in Intel's slides), making this the first test of the vertical scaling potential of 3D XPoint technology. This combined with with a new SSD controller supporting PCIe 4.0 will enable "multiple millions" of IOPS, more than doubling the throughput of current Optane SSDs. Raja also mentioned that they've made optimizations to single-sector reads, so 4kB QD1 random read latency should be improved a bit as well—but this latency is already substantially limited by the latency of PCIe and NVMe command processing.

Intel recently stated that they have not yet decided where to spun up their own volume manufacturing of 3D XPoint memory, so the second-gen 3D XPoint used in Alder Stream will still be manufactured by former partner Micron and purchased by Intel.
