Consumer NVMe devices can deliver GB/s I/O and hundreds of thousands of iops. The article's point doesn't hinge on Optane at all.

  please ask my several NVMe devices to take notice ! actual performance under Linux OS is far less than that, here

    I just tested my laptop with the Ubuntu benchmark tool on the partition editor. 3.5GB/s read on 100MB chunks.

    Single-thread, single-queue performance is much lower than the max with good NVMe devices. With increased concurrency and deeper queues, my Samsung 960 Pro which has been running my Windows 10 desktop for several years still can do 294k random 4k reads IOPS, and 2.5GB/s sequential read.

    I think that's the entire point of this article: the existing system software APIs that we use aren't a good abstraction for the capabilities of the underlying hardware, leading to poor performance.
