Mixed 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%.

Mixed 4kB Random Read/Write

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.

Mixed 128kB Sequential Read/Write

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.

    This guy is just a troll and a clown.

    ddriver - how many Optane reviews in the past 6 months have you commented on making the same arguments? I have seen you on at least 3 other sites making the same nonsensical argument about SLC SSDs. How many times has it been communicated to you that the "1000x" claim is based on the theoretical performance of the 3d Xpoint technology, not the performance of the first rollout of the product.

    Trust me, a good troll is fun every once in a while, but dude get a life.

    When a thread is blocking on IO it shows up as 100% utilized.

    Anybody know how to get Windows to recognize this drive as a system drive? I get an error from Windows saying it cannot install onto this partition - I have 260 GB of unpartitioned space available. It is not anything in the motherboard as i already called ASUS on this issue for thier WS x299 PRO/SE board. I didn't have this problem three years ago with Intel's HHHL NVMe drive. Windows 10 Preview as well as a licensed copy installed right away with no fuss.

    Well, damn that thing is fast! I want one!

    Wow, after all the talk about the price I was expecting $1000+ for the 480GB. The pricing on this is definitely on the money and the performance is clearly on a whole new level.

    But... in most client loads you'll never see it. I'd probably buy one anyway, but there is a good argument to be made just to save some cash and get the Samsung 960 PRO, which is by far the best consumer flash drive currently available.
  • extide - Friday, October 27, 2017 - link

    I agree, the price is actually pretty decent. It's ~ 1/2 the price per gig than the first SSD I bought years ago.

    WTF are you guys talking about. The 960 Pro is 2x the cost of an MX300! Probably worse reliability too, based on the "They're all dead" SSD review. I don't know why you guys and the author are so hung up on the stupid 960 Pro, a serious ripoff (unless you're a part of the 0.1% of users who would use it in a way to see superior performance).

    Again, WTF. The above 2 posters said the 960 PRO is a decent price and "by far the best consumer flash drive currently available". They are wrong, as it's 2x the cost of drives that perform the same. This is worth pointing out. That doesn't make me a troll. The 2 posters should thank me for the information. Wise people like information.

    Optane's first consumer storage drive looks very promising. That endurance is crazy impressive and is the change the industry needs to get us moving in a better direction than NAND. The prices are reasonable for the capacity and performance, but I'd like to see reductions in power consumption and (probably) heat output so its realistic to get 3D XPoint inside laptops.
