I may be not reading enough, but i still do not get the real difference for servers or consumers of optane versus normal top line SSD

Maybe I'm blind, but what kind of successor will the 660p have? Optane, or what? All that marketing stuff... "Optane is a unique combination of materials, structure and performance that other current memory and storage technologies cannot match" blablablah... As a cache für HDDs it might be interesting, but in terms of price/performance in realworld applications for the 'normal/standard user'(!!!), it makes no real sense for me. Why? Cause e.g. the Intel Optane 900P 480GB is just soo expensive (77.5cent/GB on mindfactory) and too small in capacity to serve as single system drive. The 2TB 660p with less then 9.5cent per GB(!) is totally enough for standard daily use (190 bucks for a 2TB NVME-disk as well on mindfactory). The Idea of the H10-Series could be a decent attempt, to unite the best of both worlds, but with a present max. capacity of 1TB for 160€ it's still (a bit) less interesting than a 660P-drive of equal capacity. At enterprise levels thats a totally different thing - especially cause they have way more money to buy what they need... Just my 2 cents...

There is dedicated Optane SSD - 800p series. 118 GB for what NAND SSD priced for 120 GB just 8 years ago.
