Intel Optane Memory Review – 1.4GB/s Speed & 300K IOPS for $44

Intel Optane Memory is Intel’ first phase in release of their Optane flash technology line that Intel hopes might revolutionize the flash industry.  At its most basic level, it is SSD storage that caches your hard drive with performance speeds up to 1.4GB/s, a speed that has yet to be seen for this type of storage in the industry.  The term ‘Optane’ is the new branding designation for flash products using Intel’ newest 3D XPoint flash memory. 3D XPoint just may be game changing, and in fact, it could almost be argued that Intel/Micron may have just invented a better wheel when the entire 3D Xpoint story is told.  

Intel Optane Memory SSD 32GB3D XPoint, development of which is shared between both Intel and Micron,  changes the way data is stored on flash memory, increasing data transfer speed and endurance significantly.  We will elaborate on that within this report.  Most importantly though, we hope this review provides a very easily understood study of what this will mean to you in the future, as Optane is sure leave its mark on flash technology as we see it.

Intel Optane Memory SSD PCB Back


Intel Optane Memory, as released this morning (24 Apr 17), is available in 16 and 32GB capacities and is an SSD (termed ‘Module’ by Intel), capable of caching your hard drive through its included software program, increasing PC speeds significantly. Intel’ claims are simply that a computer equipped with the Optane Memory module will increase general performance 21 times that of a hard drive alone.  More specifically,  their testing has displayed performance increases of 5x when launching of Google Chrome  and other web browsers, quicker PC start times, 67% faster game launching and loading of next level game activity, launching Microsoft Outlook and e-mail clients 5.8 times faster and 4x faster search results.  


When push comes to shove, Intel wants to tackle the world of hard drives with the Optane Memory module by making it standard in oem machines, and also available for the consumer to conduct the upgrade themselves.  79% of desktop PC’s today still contain hard drives, the remainder enjoying the speed and silence of SSD (or SSHD).  When you consider the low price of Intel Optane Memory, which is $44 for the 16GB capacity and $77 for the 32GB capacity, you can bet Intel Optane Memory will become a common feature found in new oem PC systems, those same systems already containing the latest Intel 200 series CPU. The Optane Memory module is available as of the release of this report and has a 5 year warranty. Check for availability now at Amazon.

Intel Optane Memory in PC


The Intel Optane Memory module is a 2280 M.2 SSD (80mm long) with a PCIe 3.0 x2 NVMe interface.  It contains two 128gb (16GB) 20nm Intel XPoint dies connected to a very small ASIC controller on a blue PCB.  The connector has two notches, known as the ‘M’ and ‘B’ keys, this type of SSD traditionally being seen as two lane PCIe 2.0 and capable of speeds up to about 800MB/s. Utilizing a two lane PCIe 3.0 solution, as we see here, 2GB/s data transfer speeds can theoretically be reached.

Intel Optane memory 32GB SSD Components

If you look at the first Crystal DiskMark result we posted above, you will notice the high read speed of 1417MB/s which is the first time we have seen such performance out of this specific ‘B’ and ‘M’ type M.2 connector.


Tests have recently been published on Intel’s newest Optane DC P4800X enterprise SSD.  I am going to recommend reports by my friends Paul Alcorn and Allyn Malventano . These reports do an amazing job of explaining how data no longer needs to be stored in the traditional method of blocks and pages causing write amplification, and how it is no longer a necessity in the SSDs operation to erase date before writing new data in that same space. This, and the necessary routine of ‘garbage collection’, have always been the ‘Achilles Heal’ of flash memory.  Most importantly though, both of these reports demonstrate first hand how steady state performance is a thing of the past.  New Intel SSDs have the same performance when they are first installed as when they have been in use under pressure for a period of time.


During our testing, we visually observed speed gains in system start-up, shut down, application loading, web browser and e-mail opening and use, as well as just about any other activity we commonly do on the PC.  How the Optane Memory module works is relatively simple. It stores a cache of the files associated with what you do most on the Optane Memory module, calling them up much quicker than having to go to the hard drive for them each and every time. Consider renovating a home.  Work can be accomplished faster by putting the most common tools in a room close to you, rather than in the basement or out in the vehicle. It is the same concept; the room is the cache that helps speed things up.

    Would you consider testing these with the built in Windows 10 Ready Boost alongside the plain HDD?

      Are you asking for a comparison of Ready Boost using a USB to that of Optane. You do realize that the USB has a much lower low 4k read speed than the Optane dont you… to the tune of 150-200 times. We are an SSD site but I have tested Ready Boost on my own in Windows. IMO it is more gimmic than worth the trouble. With Optane… in this case, the startup system files are readily available in the cache to equal the startup of an SSD. I might think that alone would dissuade any thought of comparison. Thanks for taking the time to comment.

        My apologies, I thought it was possible to dedicate a SSD 32 GB or smaller as a Ready Boost drive. If that is not the case then disregard. Thanks for the review. I hope Micron releases a more hardware agnostic version in the future (for AMD boards with NVMe).

        No need to apologize.. stuff like this makes us think outside the box. This actually let me in another direction to confirm something i wasn’t sure of with respect to new Optane.

    Les, I would have like to have seen the Intel DC P3700 in the Real World File Transfer Tests, having said that the Kingston DCP1000 is beyond insane at File Transfers, the Intel Optane excels at 4K low queue depth Reads and the Lowest Latencies i’ve seen to date

    Interesting. If the PCB is environment friendly then it is bigger news to me then optane memory.

    I wonder how reliable Optane is. reported that when it failed it took some data with it. I have no issue recommending SSHD over plain HDD but what is worrying me is required software component.

    So it performs admirably as a read cache, but what about as a write cache? Would the low latency be good enough to overcome the limited sequential write speeds if faced with continuous cache eviction?

    My system runs quite a bit faster than the Intel upgrade:
    9,068 MB / s Read, 14,048 MB / sec Write.
    4K Random Read 1,556 MB / sec, 4K Random Write 1,068 MB / sec.

    Romex Primo Caching Software accelerates all read / write operations with RAM and SSD caching, turbo charging any CPU to run just as fast as the RAM can go…

    People keep trying to fix the Hard Drive speed bottle neck in hardware,
    when it is much easier to fix in software, and RAM caching…

    Primo Cache works similar to the Intel device. Say you have 32GB of RAM,
    set aside 16 GB for a super sized RAM cache – all read / writes work at RAM speeds.
    Primo Cache pairs ANY SSD device to the RAM cache, for a second level of persistent caching. All the stuff you use all the time, is copied to the SSD.

    On boot up, the SSD reloads all your commonly used info into the RAM cache,
    and the RAM cache dynamically updates itself to constantly keep you at top speed.

    Go ahead and hook up your favorite 8 TB Seagate Drives to your system…
    PrimoCache ensures your Big Iron hard drives run at RAMming speed.

    There’s an option being overlooked by both Intel and MS:

    Readyboost filters small (~4K), random, oft used files onto media with lower latency than the main drive.
    The 2 drives then read/write files they are best and fastest at handling, at the same time.
    ie: A sort of ‘optimised for drive characteristics’, RAID 0…

    Now look at the random 4K read performance of Optane versus SATA SSDs and even NVME SSDs:
    Writes are not as impressive as random writes go into the DRAM cache on the SSDs, but:
    > This info can be lost in a power outage, so safer.
    > The low write speeds are only valid until the DRAM cache is full.
    > There should be an increase in SSD life as info is written to flash in 2-4 MB blocks

    I think it’s worth testing to see if Readyboost does a better job than Intel’s RST due to this filtering/Optimised RAID 0..?

    Info on overriding MS’s Readyboost settings, to test this:
    But will anyone? The ‘not invented here’ force is strong in humans! 🙂

    Everyone knows that with your software installed you basically end up using a HDD benchmark to benchmark RAM.
    Untick ‘Direct IO’ in Atto and MS’s Super/prefetch makes your block cache look stupid.
    Can your software do predictive caching, without wasting RAM by caching what’s already cached by prefetch?
    ie: Write software that switches on Superfetch with SSDs and add your SSD-saving ‘deferred writes’ and I’ll buy it!
    I will say that your caching of HDDs to SSDs is very good and universal, so if one wants to cache any HDD onto any SSD, or even RAIDed SSDs; PrimoCache is the best option.
