The Intel Optane SSD 900P 280GB Review
by Billy Tallis on October 27, 2017 9:30 AM ESTMixed Random Performance
Our test of mixed random reads and writes covers mixes varying from pure reads to pure writes at 10% increments. Each mix is tested for up to 1 minute or 32GB of data transferred. The test is conducted with a queue depth of 4, and is limited to a 64GB span of the drive. In between each mix, the drive is given idle time of up to one minute so that the overall duty cycle is 50%.
The mixed random I/O performance of the Intel Optane SSD 900P is completely unmatched. The small Optane Memory M.2 is the second fastest drive we've tested, and the fastest flash-based SSD is only a third as fast as the Optane SSD overall.

At the very end of the test, when the workload shifts to pure random writes, Samsung's fastest SSDs are able to batch the writes and dramatically improve throughput, almost enough to catch up to the slowest speed the Optane SSD hits during this test.
Mixed Sequential Performance
Our test of mixed sequential reads and writes differs from the mixed random I/O test by performing 128kB sequential accesses rather than 4kB accesses at random locations, and the sequential test is conducted at queue depth 1. The range of mixes tested is the same, and the timing and limits on data transfers are also the same as above.
The Intel Optane SSD 900P doesn't quite dominate the mixed sequential I/O test to the extent that it trounced the competition in the mixed random I/O test, but it still breaks the record with a 40% higher average throughput than the fastest flash-based SSD.

|||||||||
The Optane SSD 900P's performance wavers a bit as the workload changes, but the general trend is a gradual reduction in performance as the proportion of writes increases. The flash-based SSDs tend to show an sharper decline in performance during the first half of the test, and the good ones recover most of that performance over the course of the second half. But the low performance in the middle of the test brings the averages way down and leaves the Optane SSD alone at the top.

pls anand. just kill ddriver acc. he ruins all comment section. he's maybe "smart", but lives in another dimension, where he thinks he is only one who understands something. i bet he never ever achieved something worthy in his life. thats where all hidden anger comes from.daremighty - Tuesday, October 31, 2017 - link
I don't agree that Anandtech's approach to measure random performance. QD1 random is directly reflect the latency of memory chip (NAND or 3D Xpoint). Between the queue, there should be some idle time and it didn't explain the real random performance of device. Under random workload, the device should handle multiple random requests - it means deeper QD is more natural to explain the random performance of QD. Probably, many device would require deep QD to saturate the random, but I think it is still valid metric. I think in random, random performance with deep (64 or 128?) QD is as much important as low QD (1/2/4?). Again, low QD is just shows the NAND performance, not SSD performance.rep_movsd - Tuesday, October 31, 2017 - link
Seems like the great ddriver is an expert in all things, and his opinions of "Hypetane" are based on solid fact and "decades" of experience (of bashing intel I guess).All the people who buy Intel are idiots and those who praise Intel technology are shills...
Meanwhile, Optane and similar technologies will eventually replace SSDs and ddriver will still be grumbling about how SLC would have been better if given a chance....
Get with the times - no one is forcing anyone to buy anything Intel - and if you think anandtech fudges benchmarks, put your money where your mouth is and try doing a fraction of what they do...
Don't pour cold water on others efforts just because you have some PTSD with Intel for whatever reason...

"Get with the times"Thats a great comment!
Seems like ddriver might have gotten a timeout several days ago and yet a few of you can't seem to get over him
Just admit it, you loved his comments and want him back, or else you could get with the times and get over him
He's gone, but look at the bright side.....
I'M BACK!

Intel's caching software for Optane sucks - super finicky, not easy to integrate with an existing system and most of all requires specific motherboard to work (which I happened to have, but not the right partition layout - I dunno, technical documentation for what they want is pretty nonexistent).Luckily I stumbled PrimoCache. Downloaded a trial and had it working with my m2 Optane in 5 minutes. Made a noticeable and rather dramatic difference, even when loading stuff off of my Samsung EVO SSD. For $20 it was worth the frustration of not having to figure out Intel's poorly documented and overly fussy software. And if you don't have an Intel supported board, this lets you use Optane for caching with any board with an m2 slot.
These Optane drives would be awesome for servers - based on the experience with my desktop I now use PrimoCache on a couple of my servers and even with cheap SSDs the difference is amazing. With larger Optane drives? I should be even better. And at $120 for the server version it's by far the fastest way to add SSD caching to Windows Server. I'm extremely happy with it!

That's interesting.. wish I had known about PrimoCache when I was tinkering with the little Optane stick. Intel's software was a huge mess, and Intel was less than helpful in working through it. When I finally went to remove it and throw in the towel, neither the software nor the UEFI could remove the stuff. I wound up having to reinstall Windows.Kwarkon - Monday, November 6, 2017 - link
I'm quite curious what exact issues you had, especially with disabling Optane?mattlach - Saturday, December 30, 2017 - link
Looking at that random 4k write performance, I'm thinking a pair of these would be absolutely fantastic as a mirrored SLOG/ZIL device for my massive ZFS pool. It's very tough to predict through.Question is how they would perform on the dual socket Westmere-EP Xeons powering my storage box, with only PCIe Gen2... Probably won't make a huge difference since the write speed peaks out at about 1.7GB/s and 4x PCIe Gen2 tops out at 2GB/s.
I wouldn't mind a decent boost to sync write speeds, and this 900p seems like its tailor made for the job. No cache, so there is no need for battery/capacitor backup, and very high speed, low latency random writes...
