"Intel is taking Optane to the next level with its SSD P5800X, which it bills as the fastest SSD in the world. The next-gen Optane SSD leverages the PCIe 4.0 interface, second-gen Optane media, and a new SSD controller to deliver truly astounding performance and endurance specifications."

"Compared to the first-gen Optane DC P4800X, Intel says the 5800X offers an impressive 3X performance improvement in random read/write workloads, peaking at 1.5 million 4K random IOPS, and 3X more sequential performance at a peak of 7.2 GB/s." 

"The drive also delivers up to 4.6 million IOPS in random 512B workloads (useful for certain types of caching workloads) and up to 1.8 million IOPS in mixed workloads."

My 1982 SemiDisk (a whopping 512 kilobytes in storage:  That's 0.000000512 Terabytes for you slacker millennials) was lucky to do 1 megabytes/second in transfer rate.
