The Intel Optane SSD 800p (58GB & 118GB) Review: Almost The Right Size
by Billy Tallis on March 8, 2018 5:15 PM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.
As with The Destroyer, the average data rate of the Intel Optane SSD 800p puts it near the top of the rankings, but behind the fastest flash-based SSDs and the Optane 900p. Intel's VROC again adds overhead that isn't worthwhile without the high queue depths of synthetic benchmarks.
The average and 99th percentile latencies of the Optane SSD 800p on the Heavy test are better than any of the low-end NVMe SSDs, but it is only in RAID that the latency drops down to the level of the best flash-based SSDs and the 900p.
The average read latency of the Optane SSD 800p ranks second behind the 900p. VROC adds enough overhead that the RAID configurations end up having slightly higher average read latencies than the Samsung 960 PRO. For the average write latencies, VROC is far more useful, and helps the 800p make up for the lack of a write cache.
The 99th percentile read and write latencies of the 800p RAID configurations are on par with the 900p, but the individual drives have slightly worse QoS than the Samsung 960 PRO.
The 800p again leads in energy usage thanks to its high overall performance without the high baseline power consumption of the 900p. The budget NVMe SSDs all use at least twice as much energy over the course of the test, and the Samsung 960 PRO is closer to the budget drives than to the 800p.

Until you start running databases, multi-tenant VM environments, and large swap files for map-reduce, inference drawing, etc..xenol - Monday, March 12, 2018 - link
Yeah, let me know when the average consumer uses that.keralataxi - Monday, March 26, 2018 - link
thank you for sharing this.This site is really helpful to me and i think you have to collect more details about the topic.http://keralatravelcabs.com/tempo-traveller-taxi-s...

Rrrrrrright. So, yes, a human wouldn't perceive... the latency improvement seen on a single IOP on Octane vs. an alternative.Bravo. That's about as insightful as pointing out that a human also wouldn't notice the difference in latency between a single operation on a 3ghz CPU vs. a 4ghz CPU. Because microseconds, amiirite?
Just for your reference: this is 2018. Unless we're traveling back to 1985 and benchmarking the floppy drive on a Commodore 64, we usually measure the performance or modern by looking at the aggregate performance of thousands or even millions of operations.

When something is loading it is rarely doing 1 task. Hundreds or thousands of tasks will definitely be noticeable. You would be surprised how much goes on just loading an app...MrSpadge - Friday, March 9, 2018 - link
No, I can't remember anyone saying that. It was supposed to be an intermediate step between high NAND and DRAM.ATC9001 - Friday, March 9, 2018 - link
It very well may cost less than NAND, but no business in the world is going to sell a product that's faster for less than another one of it's products (unless it simple doesn't sell, which is surely not that case for NAND).I'm pretty excited overall...sure it's hyped up a lot, but remember the first SSDs? Took a while to figure out the controllers and such.
It's great to see the low latency...with DRAM prices the way they are *MAYBE* some enterprise customers will look to optane.
As a gamer, I'm more concerned with sequential performance and higher capacities, but for prosumers with high random workloads this might make sense.

More importantly wan't xpoint supposed to have endurance many times over an SLC nand?. The spec here is not much better than an MLC let alone SLCchrnochime - Thursday, March 8, 2018 - link
And FWIW, I value endurance(write cycle) far more than speed. So if it's as fast as SLC I'm okay with that.iter - Thursday, March 8, 2018 - link
Performance means the actual media performance, that includes P/E latency and endurance. slc has great endurance, that I myself would be more than willing to pay for, alas there is no such an option as no slc products have been made the last few years.
