The Intel Optane Memory H10 Review: QLC and Optane In One SSD
by Billy Tallis on April 22, 2019 11:50 AM ESTApplication Benchmarks
With a complex multi-layer storage system like the Intel Optane Memory H10, the most accurate benchmarks will be tests that use real-world applications. BAPCo's SYSmark 2018 and UL's PCMark 10 are two competing suites of automated application benchmarks. Both share the general goal of assigning a score to represent total system performance, plus several subscores covering different common use cases. PCMark 10 is the shorter test to run and it provides a more detailed breakdown of subscores. It is also much more GPU-heavy with 3D rendering included in the standard test suite and some 3DMark tests included in the Extended test. SYSmark 2018 has the advantage of using the full commercial versions of popular applications including Microsoft Office and Adobe Creative Suite, and it integrates with a power meter to record total system energy usage over the course of the test.
The downside of these tests is that they cover only the most common everyday use cases, and do not simulate any heavy multitasking. None of their subtests are particularly storage-intensive, so most scores only vary slightly when changing between fast and slow SSDs.
BAPCo SYSmark 2018
BAPCo's SYSmark 2018 is an application-based benchmark that uses real-world applications to replay usage patterns of business users, with subscores for productivity, creativity and responsiveness. Scores represnt overall system performance and are calibrated against a reference system that is defined to score 1000 in each of the scenarios. A score of, say, 2000, would imply that the system under test is twice as fast as the reference system.

The Kaby Lake desktop and Whiskey Lake notebook trade places depending on the subtest; sometimes the notebook is ahead thanks to its extra RAM, and sometimes the desktop is ahead thanks to its higher TDP. These differences usually have a bigger impact than choice of storage, though the Responsiveness test does show that a hard drive alone is inadequate. The Optane Memory H10's score with caching on is not noticeably better than when using the QLC portion alone, and even the hard drive with an Optane cache is fairly competitive with the all-solid state storage configurations.
Energy Usage
The SYSmark energy usage scores measure total system power consumption, excluding the display. Our Kaby Lake test system idles at around 26 W and peaks at over 60 W measured at the wall during the benchmark run. SATA SSDs seldom exceed 5 W and idle at a fraction of a watt, and the SSDs spend most of the test idle. This means the energy usage scores will inevitably be very close. The notebook uses substantially less power despite this measurement including the display. None of the really power-hungry storage options (hard drives, Optane 900P) can fit in this system, so the energy usage scores are also fairly close together.
The Optane Memory H10 was the most power-hungry M.2 option, and leaving the Optane cache off saves a tiny bit of power but not enough to catch up with the good TLC-based drives. The Optane SSD 800P has better power efficiency than most of the flash-based drives, but its low capacity is a hindrance for real-world use.

The Optane cache provides enough of a boost to PCMark 10 Extended scores to bring the H10 into the lead among the M.2 SSDs tested on the Whiskey Lake notebook. The Essentials subtests show the most impact from the Optane storage while the more compute-heavy tasks are relatively unaffected, with the H10 performing about the same with or without caching enabled.

"Why hamper it with a slower bus?": cost. This is a low-end product, not a high-end one. The 970 EVO can at best be called "midrange" (though it keeps up with the high end for performance in a lot of cases). Intel doesn't yet have a monolithic controller that can work with both NAND and Optane, so this is (as the review clearly states) two devices on one PCB. The use case is making a cheap but fast OEM drive, where caching to the Optane part _can_ result in noticeable performance increases for everyday consumer workloads, but is unlikely to matter in any kind of stress test. The problem is that adding Optane drives up prices, meaning that this doesn't compete against QLC drives (which it would beat in terms of user experience) but also TLC drives which would likely be faster in all but the most cache-friendly, bursty workloads.I see this kind of concept as the "killer app" for Optane outside of datacenters and high-end workstations, but this implementation is nonsense due to the lack of a suitable controller. If the drive had a single controller with an x4 interface, replaced the DRAM buffer with a sizeable Optane cache, and came in QLC-like capacities, it would be _amazing_. Great capacity, great low-QD speeds (for anything cached), great price. As it stands, it's ... meh.

Therein lies the BS... Optane cannot compete as a low end product as it is too expensive.. so they should have settled for being the best premium product with 4x PCIe... probably even maxing out PCIe 4.0 easily once it launches.CheapSushi - Wednesday, April 24, 2019 - link
I think you're mixing up why it would be faster. The lanes are the easier part. It's inherently faster. But you can't magically make x2 PCIe lanes push more bandwidth than x4 PCIe lanes on the same standard (3.0 for example).twotwotwo - Monday, April 22, 2019 - link
Prices not announced, so they can still make it cheaper.Seems like a tricky situation unless it's priced way below anything that performs similarly though. Faster options on one side and really cheap drives that are plenty for mainstream use on the other.

lol cheaper? All of the parts of a traditional SSD, *plus* all of the added R&D, parts, and software for the Optane half of the drive?I will be impressed if this is only 2x the price of a Sammy... and still slower.

Ultimately, to scale this I think Intel is going to have to add an on card PCIe switch. With the company currently dominating the market setting prices to fleece enterprise customers, I suspect that means they'll need to design something in house. PCIe4 will help some, but normal drives will get faster too.kpb321 - Monday, April 22, 2019 - link
I don't think that would end up working out well. As the article mentions PCI-E switches tend to be power hungry which wouldn't work well and would add yet another part to the drive and push the BOM up even higher. For this to work you'd need to deliver TLC level performance or better but at a lower cost. Ultimately the only way I can see that working would be moving to a single integrated controller. From a cost perspective eliminating the DRAM buffer by using a combination of the Optane memory and HBM should probably work. This would probably push it into a largely or completely hardware managed solution and would improve compatibility and eliminate the issues with the PCI-E bifrication and bottlenecks.ksec - Monday, April 22, 2019 - link
Yes, I think we will need a Single Controller to see its true potential and if it has a market fit.Cause right now I am not seeing any real benefits or advantage of using this compared to decent M.2 SSD.

What Intel needs to do for this to really take off is to have a combo NAND + Optane controller capable of handling both types natively. This would eliminate the need for a PCIe switch and free up board space on the small M.2 sticks. A win-win scenario if Intel puts forward the development investment.e1jones - Monday, April 22, 2019 - link
A solution for something in search of a problem. And, typical Intel, clearly incompatible with a lot of modern systems, much less older systems. Why do they keep trying to limit the usability of Optane!?In a world where each half was actually accessible, it might be useful for ZFS/NAS apps, where the Optane could be the log or cache and the QLC could be a WORM storage tier.
