Intel Optane SSD 905P 1.5TB Review - Massive 3D XPoint

Final Thoughts


The 1.5TB Intel Optane SSD 905P is the best and most interesting SSD ever brought to market, but its high cost makes it a pipe dream for many of our readers. This level of performance, in this capacity, and at this price, ensure this Optane SSD will only run in professional systems where storage performance is a bottleneck for specialized applications.




It's not the same for other 9-Series Optane SSDs. The 280GB and 480GB models are not as cheap as similar capacity flash-based NVMe SSDs, but they are obtainable for those willing to invest for the performance gains.


If your only concern is application performance and your space requirements demand volume beyond 960GB, the Optane SSD 905P is your only option. In time, we will Samsung's Z-NAND SSD, but have our doubts in its ability to deliver similar low queue depth performance. The drive we recently saw at a Samsung sponsored event should be in our hands in the coming weeks, but this drive is only 1/3 the capacity of the 1.5TB Optane SSD.



Flash-based SSDs in performance RAID can reach similar and even superior capacities, but also lack low queue depth performance. For many years, RAID was how we accelerated professional applications but NVMe technology, and later 3D XPoint memory, reduced or eliminated the usefulness of RAID. Intel's 9-Series is simply easier to work with, no complicated setup or monitoring, delivers significantly more write endurance, and delivers superior performance. In that sense, the Optane SSDs are a better overall value even though you pay more in upfront costs.
