AnandTech Storage Bench - Light

Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.

ATSB - Light (Data Rate)

The Intel Optane Memory H10 is generally competitive with other low-end NVMe drives when the Light test is run on an empty drive, though the higher performance of the QLC portion on its own indicates that the H10's score is probably artificially lowered by starting with a cold Optane cache. The full-drive performance is worse than almost all of the TLC-based SSDs, but is still significantly better than a hard drive without any Optane cache.

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

The average and 99th percentile latencies from the Optane Memory H10 are competitive with TLC NAND when the test is run on an empty drive, and even with a full drive the latency scores remain better than a mechanical hard drive.

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

The average write latency in the full-drive run is the only thing that sticks out and identifies the H10 as clearly different than other entry-level NVMe drives, but the TLC-based DRAMless Toshiba RC100 is even worse in that scenario.

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

Unlike the average latencies, both the read and write 99th percentile latency scores for the Optane H10 show that it struggles greatly when full. The Optane cache is not nearly enough to make up for running out of SLC cache.

    It's Intel still trying, and still failing, to make Optane relevant in the consumer space.

    It works in the sense that the OEMs who use this drive will be able to use the fact that customers will be getting cutting edge Optane storage. As the review says, this is a low effort solution, so it likely didn't cost much to develop, so they won't need too many design wins to recoup their costs. It also gets Optane into many more consumer devices, which helps in the long run in terms of perception, if nothing else.

    Note: most users won't know or even care that the drive itself doesn't provide faster performance than other solutions, so it doesn't really matter to Intel either. If they get the design win, Optane does gain relevance in the consumer space, just not with the small segment of power users who read AnandTech for the reviews.

    Seems it does provide faster performance in some usage cases.

    I can't stand these dumb posts where people shut down the usage for consumers. I use it all the time for OS and other programs/files. I use it as cache. I use it for different reasons. Even the cheap early x2 laned variants. I'm not in IT or anything enterprise. Reply

    It's worse than that.
    The OPTANE team clearly want to sell as many Optanes as they can.
    But INTC management has decided that they can extract maximal money from enterprise by limiting

    But INTC management has decided that they can extract maximal money from enterprise by limiting the actually sensible Optane uses (in the memory system, either as persistent memory ---for enterprise, or as a good place to swap to, for consumers).

    And so we have this ridiculous situation where the Optane team keeps trying to sell Optane in ways that make ZERO sense because the way that makes by far the most sense (sell a 16 or 32 GB or 64GB DIMM that acts as the swap space) is prevented by Intel high management (who presumably are scared that if cheap CPUs can talk to Optane DIMMs, then someone somewhere will figure out how to use them in bulk rather than super expensive special Xeons).
    Corporate dysfunction at its finest...

    I think it's too soon to say that Intel's artificially holding back Optane DIMMs from market segments where they might have a chance. They had initially planned to have Optane DIMM support in Skylake-SP but couldn't get it working until Cascade Lake, which has only been shipping in volume for a few months. Now that they have got one working Optane-compatible memory controller out the door, they can consider bringing those memory controller features down to other product segments. But we've seen that they have given up on updating the memory controllers on their 14nm consumer parts even to provide LPDDR4 support, which certainly is a more compelling and widely-demanded feature than Optane support. I wouldn't expect Intel to be able to introduce Optane support to their consumer CPUs until their second generation of 10nm (not counting CNL) processors at the earliest. Trying to squeeze it into their first mass-market 10nm would be unreasonable since they should be trying at all costs to avoid feature creep on those parts and just ship something that works and isn't still Skylake.

    Read here for an actual real world usage test. Two system with only memory difference and same input sometimes significantly different results.

    3X speed up for some tasks. I don't know about ya'll but I multitask a lot at work so I will let background stuff go while I do something else that is in front of me.

    That's too bad. I tried to tinker with the Optane caching when it launched and it was a software disaster. I wrote it off to early days stuff and put it in my kids' PC when they began to allow non-boot drives to be cached. It was another disaster and Intel's techs couldn't figure it out.

    I wound up re-installing Windows the first time and I had to redo the kids' game drive the second time. No thanks.

    The problem is you were using the proprietary HDD caching they marketed. There are so many ways to do drive caching on Windows that doesn't involve that Intel software. It's way better and smoother. even if still software. Software RAID and cache is superior to hardware cache unless you're using $1K+ add-on cards. Reply
