I think that you misunderstand the usage of the Optane, it isn't meant to be a cache for an HDD. It will serve as a cache for the NVMe SSD.
In hardware terms even an NVMe SSD's random access is slow compared to DRAM memory.
From the article:
Intel's SRT already has caching algorithms tuned for 16GB to 64GB caches in front of hard drives, so now that they have a solution for mediating access to NVMe SSDs it is simple to enable using both features simultaneously. The changes do need to be added to both the RST driver and to the motherboard firmware if booting from a cached volume is to be supported. Backporting and deploying the firmware changes to Skylake motherboards should be possible but is unlikely to happen.
