Sequential Read Performance

Our first test of sequential read performance uses short bursts of 128MB, issued as 128kB operations with no queuing. The test averages performance across eight bursts for a total of 1GB of data transferred from a drive containing 16GB of data. Between each burst the drive is given enough idle time to keep the overall duty cycle at 20%.

Burst 128kB Sequential Read (Queue Depth 1)

The burst QD1 sequential read performance of the Intel Optane SSD 900P falls in between the Samsung 960 PRO and 960 EVO. Samsung's fastest outperforms the Optane SSD by about 11%.

Our test of sustained sequential reads uses queue depths from 1 to 32, with the performance and power scores computed as the average of QD1, QD2 and QD4. Each queue depth is tested for up to one minute or 32GB transferred, from a drive containing 64GB of data.

Sustained 128kB Sequential Read

On the longer test of sequential read performance, the Optane SSD holds on to a commanding lead after the flash-based SSDs mostly slow down relative to their burst performance.

Both Optane devices show a jump in performance from QD1 to QD2, after which their performance holds steady. Samsung's 960s show very minor performance increases with queue depth, and at the highest queue depths the Intel SSD 750 comes closest to catching up to the Optane SSD.

Sequential Write Performance

Our test of sequential write burst performance is structured identically to the sequential read burst performance test save for the direction of the data transfer. Each burst writes 128MB as 128kB operations issued at QD1, for a total of 1GB of data written to a drive containing 16GB of data.

Burst 128kB Sequential Write (Queue Depth 1)

Samsung's 960 PRO and EVO drives all outperform the Intel Optane SSD 900P on the burst sequential write test, by up to 16%.

Our test of sustained sequential writes is structured identically to our sustained sequential read test, save for the direction of the data transfers. Queue depths range from 1 to 32 and each queue depth is tested for up to one minute or 32GB, followed by up to one minute of idle time for the drive to cool off and perform garbage collection. The test is confined to a 64GB span of the drive.

Sustained 128kB Sequential Write

On the longer sequential write test, the Optane SSD loses ground to Samsung's three fastest SSDs but everything else slows down even more.

Almost all of the SSDs in this bunch reach their full sequential write speed at QD2, and they are mostly differentiated by their speeds once saturated. A few drives show some unevenness during the later portions of the test, but the Optane SSD has just a minor blip in its favor at the end of the test.

    That only goes to show your thinking skills need a lot of work before they get useful.

    Pardon me for not clapping my hands and cheering at pointless mediocrity. Hopefully some day I will be able to reach that level of excellence ;)

    That's the limited mindset of today. If you applaud AMD's achievements, you have got to be an AMD fanboy, and when that same person criticizes AMD stupidity, it defines all logic, because only fanboys like AMD and fanboys don't criticize their idols, right?

    Tell ya what, when AMD invents a completely new type of non-volatile storage technology that nobody has ever put on the market before then I promise not to literally ignore the actual facts that are set forth in Anandtech's review of the product to come to some predetermined bigoted conclusion.

    AMD would probably invest in a lot, had it not been sandbagged by intel's illegal business practices over the course of decades. It was intel violating the cross-license agreement they agreed to first, and after that was no longer possible, they simply bribed the market away from amd.

    And don't me wrong. I do not "love" AMD, I do realize they only slow love for the consumer because they are not in the position intel is, which is a position they would definitely love to be in, and will abuse as much as intel does.

    My only concern about about AMD has to do with the fact that if they do better, intel has to do better too. True that AMD has a better track record, but again, that's only because they weren't in the position to do worse.

    Yawn, another butthurt "OMG INTEL ILLEGAL" delusional fanboy.

    Fact 1: AMD founder Jerry fried-chicken Sanders took kickbacks from Microsoft to testify *that Microsoft was not a monopoly* in federal court. If Colonel Sanders thinks Microsoft was never a monopoly then you know he never thought Intel could possibly have been a monopoly.

    Fact 2: Your former hero Hector Ruiz ran AMD into the ground while paying himself more than Intel's CEO was earning while conducting insider trading. His contribution was to piss away AMD's ability to fab leading edge silicon while massively overpaying for ATi. Oh, and Bulldozer... yeah that was him too. Funny how Intel must have magically mind-controlled him and the rest of AMD into all those decisions!

    People like you love to blame other people for your own bigotries and personal failings. The last thing you could do is to ever think that your Holy AMD could possibly maybe not be perfect.

    Thanks but my butt is fine, and branding makes a zero difference in my purchase decisions.

    You however are obviously a butthurt intel fanboy who got triggered by the very mention of intel's misdeeds, which are not a conspiracy theory but a PUBLICLY KNOWN FACT.
  • eddman - Friday, October 27, 2017 - link

    You are such a proponent of "facts", just like when you said Note 7 was sabotaged by intel and/or western powers to hold back samsung's and/or south korea's advancements without any shred of evidence.

    You simply do not like whatever intel, nvidia, (insert X,Y,Z company I don't approve of) make and try your hardest to dismiss them by pretending you are "criticizing" them and then trying to cover your personal attacks against other posters as "sarcasm" and by coming up with words out of a 14-years old's vocabulary like "hypetane".

    It would've been ok if you actually were a kid but you claim to be an expert of decades in pretty much everything. Very professional.
  • ddriver - Friday, October 27, 2017 - link

    OK, you seem to have a problem with exploring eventualities. Do you have a problem with evolution? Or the big bang? Those are after all, just theories, some claim they make sense and have some factual or logical support, but they are essentially still just theories and not facts.

    My bet is you don't. You don't really have a problem with claims that are unsubstantiated by evidence, you only have a problem with those of them that are not endorsed by the status quo.

    Because you are a conformist. Which is also why you have a persistent problem with me, because it annoys you that I stand up to conformity and cultivate individualism. How dare I?

    Speaking about 14 year olds, I am pretty sure that unlike you, a 14 year old would get the joke. Optane - over-hyped -> hypetane. Probably even a 5 year old would. But not you, to you it is absolutely inappropriate for someone to mock the lies of a monopoly. Because you are a conformist. You are obligated to show respect and admiration. And you get triggered when someone does not.

    Good job trying to pretend you just said it as a "theory". You mentioned it as an absolute, 100%, undeniable fact without ever using words like "maybe", "could be", "possibly", etc. and belittled anyone who said otherwise.

    As for the "joke", only a kid would come up and use something like that, right there with words like "poser", etc. You are such a professional critic that has to resort to such childish words. At least you finally acknowledged that you simply do all this for mocking purposes.

    Also, changing from the word "sheep" to "conformist". It seems you found a way to hide your insults. Yes, every single person in the world is a "conformist" except you. I'm sure your spamming on anandtech will finally get rid of the evil corporations.

    "you mentioned it as an absolute, 100%, undeniable fact"

    That's your theory. Unless I explicitly said it is "absolute, 100% undeniable fact", it is only your insinuation.

    "You are such a professional critic that has to resort to such childish words"

    Nah, I just don't limit myself, foolishly believing that being "serious" will make me any smarter, you know, like you do. That's dumb, and I don't feel urges to be considered smart by dumb people.

    "It seems you found a way to hide your insults"

    Nah, I just don't like insulting sheep by comparing them to you. Unlike you, a sheep cannot help but be a sheep. Also, you clearly don't know what "spamming" means, and clearly ignorant of what else I do in regard with the "evil corporations" aside from "spamming".

    I am pretty sure if I was spamming or in violating the site rules in any other way, I would have been banned, don't you think? I haven't even gotten warnings, public or private. Let me know, if I am doing something wrong, would ya AT staff?

    You do not care about what others think about you, that's why you keep commenting and boasting about yourself. You are a typical ego driven person. Keep spamming. AT cannot be bothered with you. Reply
