AnandTech 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.

ATSB - Heavy (Data Rate)

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.

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

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.

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

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.

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

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.

ATSB - Heavy (Power)

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.

    Hypetane! Reply

    optane = hypetane
    x-point = xtra-pointless

    It keeps getting worse and worse instead of getting better. The next x-point iteration may slip below nand even in the few strong points of the technology.

    Also, it doesn't seem that enterprise is very interested in intel's offering, seeing how they struggle to cram the product in market niches where it is xtra-pointless, I'd go on a limb and assume that's not because of love for consumers or skipping on them fat enterprise product margins.

    Also, it seems that intel gave very misleading information not only in terms of performance, but also regarding the origin of the technology. The official story is its development began in 2012 as a joint venture between intel and micron.

    That however is not true, x-point can be traced back to a now erased from history company named Unity Semiconductors, which was flogging the tech back in 2009 under the CMOx moniker.

    Courtesy of archive.org, there is still some trace of that, along with several PDFs explaining the operational principle of what intel has been highly secretive about:

    https://web.archive.org/web/20120205085357/http://...

    All in all, the secrecy might have to do with intel's inability to deliver on the highly ambitious expectations of the actual designers of the tech. It is nowhere near the 200% better than nand density, in fact it seems at the current manufacturing node it won't be possible to make more than 256 gb in m2 form factor, which is 8 times less than mlc nand or 24 times less than what was projected in 2009. Performance is not all that stellar too, a tad lower than what slc was capable at back in 2012, thank the gods nobody makes slc anymore, so there's a ray of sun to make xtra-pointless hypetane look good on paper.

    Rambus renamed it to ReRAM according to this article in 2015, so it would seem the tech lived on through Rambus after the aquisition of Unity Semi.

    But I'm not sure if it's the exact same tech as Intel's.

    Check the PDFs, what little intel posted about it is all there. They may have licensed the tech from rambus. It is not like rambus does anything other than patent milking anyway. Reply

    "Coincidentally", rambus bought unity in 2012, exactly when intel allegedly started developing... Reply

    Not everyone remembers a few sticks of RAMBUS RDIMMS for some Pentium 3 boards costing $500-$600 a stick back in '99-'00....; and being outperformed by DDR. Nice job, RAMBUS! Reply

    Am I reading it right? Was Cross-point memory supposed to be cheaper than NAND? Reply
  • WinterCharm - Thursday, March 08, 2018 - link

    Yes. But I guess we won't see that for a while.

    Latency and power consumption are great... but speed and capacity leave a lot to be desired. When MacBook Pros have NVME drives capable of 3.2 GB/s (yes gigabytes) at a 2TB capacity... Optane is far behind.

    There are some advantages, but I expect that Intel will need to do a lot more work before these are cheaper, faster, and have higher capacity.

    That said, latency is what users notice. Max speed is a rarely encountered scenario in most user workloads. Reply

    No human notices microseconds. Delay becomes noticeable at about 10-20 msec, depending on the individual's reflexes, becomes annoying at about 50 msecs, and becomes detrimental at 200+.

    10 mseconds is 10000 microseconds. Hypetane improves things in the double digit microseconds range. Humans cannot notice that, not today, not in a million years.
