Intel's Optane Memory H10 SSD will begin shipping soon in pre-built systems from major OEMs, so Intel's ready to unveil more detailed information about the drive first previewed earlier this year at CES. The Optane Memory H10 is a significant change from the existing Optane Memory family of products, and is a unique 2-in-1 SSD combining 3D XPoint memory and QLC NAND flash memory on a single M.2 module. The H10 is essentially a consolidation of the existing Optane Memory M10 module and the Intel 660p QLC SSD onto a single drive. The Optane portion of the drive is intended to be used as a cache for the QLC portion of the drive, using the Optane Memory caching drivers for Windows that Intel has previously pitched for using with standalone Optane Memory M.2 modules and mechanical hard drives. Until now, Optane products have been difficult to fit into ultrabooks where two M.2 slots may be challenging and a 2.5" hard drive is out of the question.

The Optane Memory H10 will come in three varieties, with QLC NAND capacities ranging from 256GB to 1TB. The 256GB model will have 16GB of Optane storage while the 512GB and 1TB will both have 32GB of Optane storage. All three capacities are implemented as single-sided M.2 modules, with approximately half of the card dedicated to the Optane controller, media and PMIC, while the other half contains the Silicon Motion SM2263 controller, DRAM and QLC NAND. The card as a whole has a PCIe 3.0 x4 interface, but each of the two SSD controllers gets just two PCIe lanes. Intel's caching software will support reading and writing data from both Optane and QLC simultaneously, so they rate the H10 for up to 2.4GB/s sequential reads even though neither half can exceed 2GB/s on its own.

Write Endurance     300 TB

For random I/O, Intel rates the H10 for 32k random read IOPS and 30k random write IOPS at queue depth 1, and 55k IOPS for both at QD2. The random read ratings are significantly higher than we've measured from the Intel 660p QLC SSD, but are only a fraction of what the 32GB Optane Memory is capable of on its own, so Intel's clearly trying to provide a more realistic composite that reflects how real-world usage won't be able to entirely stay within the Optane cache.

Idle power is rated to be under 15mW total, the result of both SSD controllers aboard the H10 being able to hit single-digit mW power when PCIe L1.2 sleep states are used.

Write endurance ratings will go up to 300 TB on the 1TB capacity, a 50% increase over the QLC-only Intel 660p. The QLC portion of the Optane Memory H10 will still be using SLC write caching, but the high-endurance Optane cache will take a lot of write pressure off the NAND flash. The warranty period is the same 5 years that the Optane Memory M10 and Intel 660p carry individually.

System Requirements

The Optane Memory H10 has narrower system requirements than previous Optane Memory products. Intel has always required a Kaby Lake or later system to use their Optane Memory caching drivers, but the previous Optane Memory drives were still plain NVMe SSDs at heart and could be used as either standalone drives or with third-party caching software in any machine supporting NVMe SSDs. Since the H10 bundles two drives on one card, it will require a host slot that provides all four PCIe lanes and supports operating them as two ports of two lanes each. Intel's caching functionality for the Optane Memory H10 requires their RST version 17.2 drivers, the first release series to enable Optane Memory caching of NVMe SSDs instead of just SATA drives. (Also the first release series to support Pentium and Celeron branded processors.)

Officially, Intel is requiring the H10 to be used with a 300-series PCH and an 8th Gen Core U-series mobile processor, but that mostly reflects which platforms will be offering the H10 at launch. Intel has not yet committed to bringing the H10 to the retail market for use in desktop systems, but they have been laying the groundwork and many 300-series motherboards have firmware updates available to enable booting from the H10. (The first public leak of the Optane Memory H10 product name came from motherboard manufacturers advertising support on 300-series desktop boards.) Desktops with 300-series chipsets and at least two M.2 slots can already achieve essentially the same setup as the H10 using an Intel 660p and Optane Memory M10 module, so there isn't strong pressure for a retail release of the H10. The hardware features Intel relies on for Optane Memory caching and NVMe RAID on consumer platforms have been present since Skylake 100-series chipsets, but Intel has shown little interest in rolling out firmware support to older platforms.

Our Optane Memory H10 review sample is arriving today, and we will have a full review out later this month.

    I'm really curious to see what kind of real world latency improvements this would provide over a more conventional MLC/TLC/QLC only SSD. It potentially be great for a boot drive.
  • austinsguitar - Wednesday, April 10, 2019 - link

    the performance and write endurance on these qlc devices is an abomination, and you and i know that these things will not sell. there is zero reason for these drives to exist. end of story.
    EDIT: people thinking these will be affordable, these know this is intel's puppet optane. it will come at a price. that defeats the purpose of qlc entirely.
  • Kvaern1 - Wednesday, April 10, 2019 - link

    That's what you said about TLC.
  • austinsguitar - Wednesday, April 10, 2019 - link

    actually no it isnt XD. tlc can now fully saturate pcie3x4 speeds, and at the time tlc had only sata 3 and m.2 speeds to go by, and they could fully saturate those lanes. qlc can "not" do this. this makes that argument invalid.
  • qlum - Wednesday, April 10, 2019 - link

    From my understanding tlc can't saturate the speeds on its own but the slc cache can for long enough in most cases. That being said tlc did get a lot better over time and I don't doubt that qlc will get much better over time as well.
  • Jorgp2 - Wednesday, April 10, 2019 - link

    That's what the Optane is for.

    Optane has insane write endurance, and with enough of a write cache it will take most of the brunt.

    The QLC is basically a victim cache in this situation, and even then they have a lot of overprovisioning.

    I personally wouldn't use this as an OS drive, it's better suited for WORM storage.
  • Samus - Thursday, April 11, 2019 - link

    Yeah, if priced right, this could make a really good gaming drive, too, as the boosted IO hits from the Optane cache could load common libraries and maps as fast or faster than many more expensive SSD's. Even QLC has decent sequential transfer rates.
  • dromoxen - Tuesday, April 16, 2019 - link

    I have a Tin for that (fishing). These may not not make much sense generally but for thinl light laptops with only one m2 slot, they should be great. I can also see the capacity's (going up) and price dropping a lot over the next years. Builtin, sealed laptops , like phones.
  • goldenatom - Wednesday, April 10, 2019 - link

    Sorry, what you keep saying just isn't supported by the available data.
  • mczak - Wednesday, April 10, 2019 - link

    I don't quite share your thoughts about QLC - if the pricing is appropriate. Things like the intel 660p 1TB/2TB imho provide quite excellent value (but yes, for write heavy scenarios they aren't what you want).
    That said, it seems like intel is trying to push these H10 ssds as somewhat of a high-end solution - faster than tlc nvme ssds, and if I'd have to guess the price will reflect this.
    And imho that's not going to fly, you'd be near certainly better off with a ordinary nvme tlc ssd like a 970 Evo for example. The H10 might be faster for some things, but overall a tlc nvme ssd will offer much more consistent performance.
    FWIW I think intel is still desparately trying to find a market for optane in client space, which doesn't really exist (now if you could get something along the lines of optane persistent memory there, that would be interesting...). Unless intel is trying reverse revenue tactics on these H10, I don't think they are really going to sell... But I'll reserve final judgment until I've seen the reviews.
