The Intel Optane SSD 900p 480GB Review: Diving Deeper Into 3D XPointby Billy Tallis on December 15, 2017 12:15 PM EST
AnandTech Storage Bench - The Destroyer
The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test. These AnandTech Storage Bench (ATSB) tests do not involve running the actual applications that generated the workloads, so the scores are relatively insensitive to changes in CPU performance and RAM from our new testbed, but the jump to a newer version of Windows and the newer storage drivers can have an impact.
We quantify performance on this test by reporting the drive's average data throughput, the average latency of the I/O operations, and the total energy used by the drive over the course of the test.
The average data rate of the 480GB Optane SSD 900p on The Destroyer is a few percent higher than the 280GB model scored, further increasing the lead over the fastest flash-based SSDs.
The 480GB Optane SSD 900p shows a substantial drop in average latency relative to the 280GB model, allowing it to score better than any flash-based SSD. For 99th percentile latency the 480GB model scores slightly worse than the 280GB, but both are still far ahead of any competing drive.
The two capacities of Optane SSD 900p have essentially the same average read latency that is less than half that of any flash-based SSD. For average write latency, the 480GB model sets a new record while the 280GB performed worse than it did the first time around, but still faster than anything other than the Samsung 960 PRO.
The 99th percentile read and write latency scores for the Optane SSD 900p are all substantially better than any flash-based SSD, even though the 280GB's results again show some variation between this test run and our original review. The 99th percentile read latency scores are particularly good, with the Optane SSDs around 0.5ms while the best flash-based SSDs are in the 1-2ms range.

Nottheface - Monday, December 18, 2017 - linkSo are the origins of xpoint memory here as claimed:
one last point
There's been so much speculation about what XPoint actually is. Well, it might be Cross-Point memory, pretty well documented few years ago - here . Unity Semiductor where this research has been conducted was acquired by Rambus in 2012 and, one year later, Micron and Rambus signed agreement giving Micron access to all Rambus patents (which would include Cross-Point IP), details here. The wording used ("... granted to Micron and its subsidiaries") would also explain why XPoint venture is majority-owned by Micron."
Nottheface - Monday, December 18, 2017 - linkSo from this:
emvonline - Tuesday, December 19, 2017 - linkNOT: XPoint is the same memory Micron and Intel were working on 10 years ago. Unity/rambus work is not at all relatedl. Side note: Intel owns the Name X point and licenses it to Micron. Intel owns the IP jointly with Micron.
emvonline - Monday, December 18, 2017 - linkReal world numbers:
I looked at a different website and the numbers showed large impacts on benchmarks. But if you look at actual gaming service times, boot times, or load times, Optane is faster but not noticeably faster (<10% difference). Could I easily tell the difference between this and other NVMe SSDs when gaming?
djayjp - Tuesday, December 19, 2017 - linkNope.
djayjp - Tuesday, December 19, 2017 - linkYou wouldn't even be able to tell the difference between this and the budget sata SSDs
emvonline - Tuesday, December 19, 2017 - linkI agree... would love to get Anandtech to agree publicly
albert89 - Thursday, January 4, 2018 - linkIntel have given me more reasons why their optane series is nothing more then a price gouge.
And non of the paid up Intel fangirls like Jays2cents, Linus Gordon from PCworld, TomsHradware etc, are going to convince me otherwise.
Chaser - Thursday, January 25, 2018 - linkTomshardware paints a completely different picture on rather unique user experience these drives provide gamers and enthusiasts.
