Intel Optane don’t excel at sequential read/write speed as compared to a fast PCI-E 4.0 SSD. But Optane has a huge advantage when it comes to latency and seek time, it is in a league of its own. So if you are looking for faster loading time, Optane should offer that. Conventional NAND based SSDs have been improving on sequential speed, which does not really improve responsiveness, at least not anywhere close to Optane. Which is why Optane tends to dominate benchmarks that don’t just focus on pure transfer rates.That Intel Optane 900P SSD from 2017 may really be ultra fast, I have never seen one.
However, seeing a 5 year old niche Intel product with a much higher score than a Samsung 980 Pro reminded me why I don't trust Bapco and PCMark series of benchmarks: somehow, Intel branded products score much higher than other brands. Somehow, 0.1 second difference in a specific product feature in Intel branded product leads to hundreds or thousands of higher score in the overal score for the Intel branded product.
On the other hand, whatever additional features products from other brands have, they don't get "special points".
