AnandTech Storage Bench - Light

Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.

ATSB - Light (Data Rate)

The Intel Optane SSD 900P doesn't come in first place for overall data rate on the Light test, until the drives are filled and the average data rate of all the flash-based SSDs takes a big hit.

ATSB - Light (Average Latency)ATSB - Light (99th Percentile Latency)

The average and 99th percentile latencies of the Optane SSD on the Light test are on par with the top flash-based SSDs when the test is run on an empty drive. When the drives are filled before the test, the flash-based SSDs slow down enough that the Optane SSD takes first place easily, with an especially wide margin on the 99th percentile latency.

ATSB - Light (Average Read Latency)ATSB - Light (Average Write Latency)

The average read latency of the Optane SSD 900P on the Light test is merely tied for first place, when the test is run on an empty drive. When the drives are filled, the Optane SSD has half the average read latency of anything else. The write latency situation is quite different; whether or not the drives are filled, most of the top flash-based SSDs are able to fit the bursts of writes in their caches and deliver better latency than the uncached writes of the Optane SSD.

ATSB - Light (99th Percentile Read Latency)ATSB - Light (99th Percentile Write Latency)

The 99th percentile read latency of the Optane SSD 900P on the Light test is tied for first place when the test is run on an empty drive, and leads by more than 60% when the drives are filled before the test. The 99th percentile write latency lags behind the top flash-based SSDs a bit, but nowhere near enough to be noticeable: the latency is still an order of magnitude lower than SATA SSDs.

    I bet you're still pissed we don't have flying cars. OMG, do you go to every new car unveiling and talk about how crappy each new car is because we were supposed to have flying cars by now?

    when you do huge particle simulations you will want the fastest SSD you can get.

    I've been doing that, for VFX as well as multiphysics simulations for over a decade. It has always been an in-memory thing. It doesn't seem they simulated it, it seems they read baked simulation data, and stored in some insanely inefficient manner at that.

    As I implied, this has got to be a new record in rigged benchmarks. Shame!

    Sigh, the Optane drive didn't improve the performance of reading the data into the simulation. The simulation required (significantly?) more RAM than the system had. They put a big swap file on either a 960 PRO or on the Optane drive. It probably doesn't even matter where the simulation data was stored.

    Well, they should have bought moar ram then. Then maybe they could have kept that CPU busy at 100% and get much better time.

    I mean it is not like hypetane offers terabytes of capacity. Topping at 480 GB - that's entirely doable in RAM. More expressive - sure, but nonetheless a perfectly sensible investment if you are doing such simulations. It will pay for itself, as RAM is tremendously faster, and also doesn't wear, at least nowhere nearly as much as xpoint does.

    For that particular case, sure, maybe more ram is the way to go, but there are plenty of cases where the drive is better, like several of the ones I mentioned above. Most of those rely on the non-volatile aspect, which obviously RAM doesn't have.
  • ddriver - Friday, October 27, 2017 - link

    As I said - it has its advantages and uses. I also said I might even buy it.

    And the only reason I call it hypetane is because intel shamelessly lied about it, and continues to cheat in order to make it look good even after it became evident that it is not anywhere nearly as good as they initially claimed, and call me old-fashioned, but I have a problem with that.

    It boggles the mind that people around here have such a problem with me just because I don't have my tongue up intel's rectum...

    BTW, 1.1 billion particles, presuming the simulation is ran in FP64 mode, with x y and z coordinates for each particle would only require about 24 gigs of ram.

    Which raises the question, did they allocate each of those points on the heap or something?
  • ddriver - Friday, October 27, 2017 - link

    Opsie, silly me, it would take another 24gb for the vector of force for each particle. Now it is a little more plausible that 64gb might not be enough.

    Sure, in a perfect world you buy more RAM. But if you are in a situation where you don't have infinate cash and you can buy more RAM at $7/GB or an Optane SSD for ~$1-2/GB then Optane begins to look a bit more appealing. A 480GB drive running as cache for $600 vs 480GB of DDR4 at $3350.... that would make almost anyone thing twice.

    Or in the case of my work, we have a bunch of clustered servers, and we are maxxed out on ram but not yet ready to do a server upgrade (hoping to get 2 more years out of them), but we need more fast cache for a bunch of different applicaitons. The idea of running those caches on this kind of SSD sounds a lot more appealing than running on traditional SSDs.

    But yes, when we upgrade servers, we will simply have more RAM on board. That is the obvious solution. But when a motherboard can only hold 256GB of RAM and you need more... life is often about compromises, and Optane tech sounds like a good compromise. But what you would use this for in daily life or in a normal computer? Man, that totally beats me! This product is almost too cheap for what it is good for (business class SSDs typically cost more than $1.25/GB still and are far slower than consumer SSDs), and completely useless and overpriced for that they are advertising it for.
