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.

    Not QUITE true.
    Apple has done it (IMHO very successfully) in part because
    - they understand something of the data patterns and
    - already had tech in the file system to move hot data (hot file system data AND hot files) to the fastest part of the medium and
    - they were willing to include ENOUGH flash (128GB) and fast flash; they didn't cheap out.

    But yeah, the solutions sold by Seagate were not (in my experience) very impressive, especially considering the ridiculous premium Seagate charged for them.

    What you CAN do on Apple systems (and I have done, very successfully, multiple times) is to fuse external SSDs with other drives (either other external or an internal HD) and this behaves just like a native fusion drive, you can even boot off it. This means you can retrofit fusion even to old macs (eg I have a 2007 iMac running a fusion system based on an SSD in an external FW-800 enclosure, fused with the internal 320GB drive).

    Sounds like Apple Fusion drive. Very difficult to do well on drive-level, much easier to do well with some OS support and filesystem level.

    Afaik people have been relatively happy with their Fusion drives, though personally I find them horribly expensive. Then again, that applies to all Apple storage options, they always feel insanely expensive.

    Optane performance is good in some ways and disappointing in others. I'd like to see the technology improve since NAND endurance is a problem that warrants a solution. Maybe Optane isn't that solution.
  • Reflex - Friday, March 9, 2018 - link

    Optane basically is a variation of Phase-Change Memory. It's been around a long time, but Micron/Intel have finally managed to make it in large enough capacities to productize it out of niche markets. There are other contenders for next gen memory &storage, ranging from MRAM (magnetic memory) to ReRAM to racetrack memory (HP has claimed to be on the edge of productizing that for about four years now).

    I am just happy one finally got out there, an it is in pretty good shape for a first gen product. Hoping this gets others to get serious about bringing alternative storage methods to market soon.

    At least the 860 EVO and Pro improved endurance a lot for consumer.

    600TB 860 EVO 1TB
    1.2PB 860 Pro 1TB

    they can easy do 4x that especially the Pro drive (they was been Really conservative before, mainly so it did not affect the sales of there enterprise drives)

    heck the 840 Pro did was 2PB before it died suddenly (but it did all that with 0 read errors)
  • Araemo - Friday, March 9, 2018 - link

    Can we get the consistency scatter plots for this drive? Those are an awesome tool to gauge the real world 'feel' of the drive.
  • Billy Tallis - Friday, March 9, 2018 - link

    They're an awesome tool to exaggerate the impact of garbage collection pauses on flash-based SSDs. Real-world usage doesn't involve constant writes to a full drive. Those random write consistency graphs often show interesting things about how drives handle GC, but they're a horrible way of ranking real-world performance of SSDs.
  • Zinabas - Saturday, March 10, 2018 - link

    As a thought the best case to use these in... would be an AMD Ryzen system with (Fuzedrive) the new software that manages all the drives as one volume. The small capacity would be automanaged by software and would be swapped to fit whatever you're playing at the time.
  • emvonline - Monday, March 12, 2018 - link

    so there doesnt seen to be a clear difference in real world applications. its faster with lower latency but does not always show up. could you cleary pick the optane drive vs samsung 960 in a blind test everytime running games and office apps?
