AMD StoreMI – An Introduction

Source: AMD StoreMI Users guide

StoreMI from AMD is a Storage Performance Enhancement Technology. What StoreMI stands for Store Machine Intelligence Technology and is aimed at enhancing the responsiveness and speed of traditional mechanical storage devices.

AMD claims that the speed and responsiveness can be enhanced to the levels observed with SSD drives using AMD StoreMI. In fact, SSDs are the fastest option that offers the highest data transfer speeds. However, not everyone can opt for SSDs. They are quite expensive and come with limited storage capacity. On the other hand, the mechanical storage devices offer you a larger storage size and quite affordable at that. But, the data transfer speeds that they offer are quite slow.

The StoreMI technology from AMD combines both these technologies and thereby offers you the best of both worlds. It makes use of advanced machine learning intelligence and uses an automatic tiering technology that analyses the data blocks. The blocks that are accessed most are moved to the faster storage tier.

If you find those details out of reach for understanding, what it means is that AMD Store MI offers you the speeds almost equivalent to SSD speeds. The technology tracks the storage requirements in real time and handles the movement of the blocks between the tiers depending upon the usage.

AMD StoreMI vs Intel Optane: Whats the Difference?

In a way, both of these technologies offer similar solutions and address a specific issue, storage throughput. While Intel’s solution is a hardware/software one, AMD’s solution is primarily a software offering.

Intel Optane Smart Response System – An Overview

Optane Memory from Intel is a new memory management technology launched recently. Just like the StoreMI technology launched by AMD, even Intel Optane Smart Response memory also works to achieve a common goal. And needless to say, the goal is to provide super-fast memory and better IOPS.

Intel has been continuously introducing better options to improve the performance of your computers and other devices. The latest introduction is Optane Memory. The new technology standard was launched along with the 7th-Gen Intel Core processors. What exactly is Optane Memory? Well, just like AMD’s StoreMI technology, it can be a little confusing to understand it if you are not someone well versed with the memory (memory) technology used in modern hardware.

Optane memory is a new generation of hyper-fast memory modules, combined with caching software. In fact, it can confuse you with the term module. But, in essence, the Optane memory is a memory in itself but is marketed in the form of an M2 card. The memory module can only be used on a compatible motherboard. The motherboards currently supported include Intel 7th generation and 8th generation chipsets. Some examples include the latest i3, i5, and i7 chipsets.

One of the features that make Optane Memory one of the best options is it achieves low latency and high performance. It delivers that by making use of 3D NAND fabrication techniques. The functionality of the Optane memory is all about working as a cache memory bridge. It primarily operates in the form of a bridge between RAM and the physical storage. This ensures a faster data transfer between the components – memory, processor, and storage. In essence, the Optane Memory works as an add-on instead of working as a separate entity. It does not replace any of your components but improves the overall speed and performance. It works as the next generation version of Intel Smart Response Technology.

Intel is planning to offer the speeds almost equivalent to the SSDs with its Optane Memory powered by Intel Smart Response technology.

How Do Intel Optane Memory and AMD StoreMI Work?

Both AMD StoreMI and Intel Optane Memory come with a single objective – offering faster data speeds. Both of them attempt to emulate the performance of SSDs regarding performance and come almost near the speeds. However, they do have a few inherent differences as well.

Some interesting differences include –

  • AMD StoreMI provides you with a tiered storage option, while Intel Optane Memory is a cached storage option.
  • Both technologies effectively accelerate HDD performance to near SSD levels.
  • An important point to consider that, with StoreMI being a tiered storage solution you get to see both reads and writes at SSD levels without sacrificing the space of the SSD. Optane only accelerates reads.
  • In case of any failure of the hardware underneath, AMD will lose all of its data and can even corrupt the HDD. The Intel Optane memory, on the other hand, will only lose the recent data, if the Optane module fails. It will not affect the HDD data and leave it working consistently.
  • Frankly, SSD technology has become so good in the past several years that SSD failure is highly unlikely, the HDD is more likely to fail first. Also, the caching approach taken by Intel writes far more often to the SSD, whereas StoreMI’s Tiering approach does not cause the “Caching Thrashing” that may occur when a cached SSD drive is full to capacity. However, if the HDD fails, the same problem exists for both ISRT and StoreMI. If an SSD fails because it has a loose cable or loses power, however, StoreMI will restore to full operation again once the issue is resolved, i.e., this is only an issue with drives that die entirely and don’t come back.
  • AMD StoreMI is limited to 256 GB of tiered SSD storage capacity, but in Intel Smart Response Technology the cached storage is limited to 64 GB. The users can upgrade the StoreMI to a 1TB version for AMD Systems called FuzeDrive for AMD Plus available on the Enmotus website.
  • If you are looking for a data mirroring option, the Intel Optane Memory or ISRT lets you have an excellent mirroring volume within a drive. AMD StoreMI does not offer it though – unless you opt for a separate RAID hardware option.
  • For users not worried about data redundancy/backup, StoreMI is probably a better solution as you get to use more effective storage utilization (i.e., the total storage of all drives).
  • If you are looking to get the most out of both speed and capacity, StoreMI is the best option. It also operates faster than a cache as it uses far fewer CPU cycles under heavy loads.
  • ISRT runs below the OS. That would mean, it runs at the system ROM level. Thus the OS corruptions will not have any effect on the functionality of the memory. This may not be true in case of AMD StoreMI. It runs at the bootloader and kernel driver level. It will have components that run after OS is loaded. Thus, if the OS develops issues, you would need an identical OS installation.
  • ISRT is also a driver level implementation just like StoreMI. Only the configuration part runs in the optional ROM.
  • ASMI is transferable to any similar 400 series system – it does not have to be the same. It is also possible to transfer to a 300 series system with the FuzeDrive version if done correctly.
  • StoreMI runs at the kernel driver level, meaning it runs after the OS has loaded – if your OS has an issue you may not be able to access the data without an identical OS installation to remount the drives.
  • If the OS breaks, you can load a new OS with StoreMI installed and view the tier to access its data. You can also access it from WinPE or WinRE environments using the driver.
  • StoreMI is far less dependent on the BIOS and does not require an option ROM. ISRT operation depends on the correct BIOS version and support.
  • ISRT also runs as a kernel driver and is subject to the same OS meltdowns with no lesser risk.

Those are a few differences and similarities between AMD StoreMI and Intel’s Smart Response Technology (also known as an Optane memory from Intel). Please note that bot the technologies are designed to work with the same result, but they do have different functionalities and features. We assume the above discussion should ideally help you choose the options that are right for you. Ultimately, they are meant for the same goal.

Before We Wind Up

Well, both AMD and Intel have been attempting to surpass one another in a game of one-upmanship. It should be quite evident from the frequent product launches that they come with and the timing chosen for these launches.

In any case, whether you are opting for AMD StoreMI or ISRT from Intel, it is you as a customer who will end up getting benefitted with an improved performance level – almost equivalent to SSDs. Choose the option that best suits you and share your experiences with us.


Since this article was written, Enmotus has introduced a version of FuzeDrive that now supports Intel Platforms (6th, 7th and 8th Gen Processors), so that Intel users are no longer limited to using the small Optane Modules (we must note that Optane modules are very high quality and work very well with FuzeDrive). Now Intel users can benefit from the latest NVME and SSD technologies and capacities available from all Flash manufacturers.
