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.

Yup, there's the ddriver we all know touting yet another set of unverifiable qualifications that proclaim relevant experience. From getting first pick of hard drives off the pallet at the shipyard to system security and now a decade of multiphysics simulation experience, this shamless self-promoter has done it all and is a SME in everything.It's too bad you're so transparently trying to set a new record in rigged life experiences. Shame!

You make a persuasive argument :)I criticize intel, that is great, therefore I suck, regardless of how grounded that criticism is.
You criticize me, who sucks, therefore you are great, like intel, regardless of how baseless your criticism is.
I wish I had such lowly and trivially attainable goals in life as you do. That would make things so much easier. I'd basically have to cheer and clap hands at my own stupidity to feel accomplished. Must be nice...

The number of times you've replied in this article alone make it clear you serve no useful purpose to the world.ddriver - Friday, October 27, 2017 - link
And I guess you responding to so many of my comments if just to whine about it makes you very useful, right? LOLCheapSushi - Friday, October 27, 2017 - link
Wouldn't be a AnandTech article without him. I pretty sure nearly every single one has some cynicism from him.ddriver - Friday, October 27, 2017 - link
Go and check and come back with the results.BrokenCrayons - Friday, October 27, 2017 - link
I like the Optane articles the best when it comes to ddriver. They predictably draw him out and while in the context of Optane, he's even easier to manipulate than usual.ddriver - Friday, October 27, 2017 - link
Oh wow, so you are manipulating me now. You mastermind you.Good thing I come out of my troll cave so you can ride that white steed of yours into glorious battle and once again find purpose in life, heroically championing for the dummies of mediocrity :)
All hail the brave sir Dumb-a-lot.

I can tell you feel like you've lost by the way you're resorting to childish name calling.sonny73n - Tuesday, October 31, 2017 - link
OMG ddriver. I've stopped reading your posts after page 3, but at page 8 now I'm still seeing your rantings. You definitely have serious issues.
