Back in April of this year we first took a look at the storage performance of the then-new X470 chipset for the 2nd generation of Ryzen processors. Allyn dove into NVMe RAID performance and also a new offering called StoreMI. Based on a software tiered storage solution from Enmotus, StoreMI was a way for AMD to offer storage features and capabilities matching or exceeding that of Intel’s mainstream consumer platforms without the need for extensive in-house development.

Allyn described the technology well:
AMD has also launched their answer to Intel RST caching. StoreMI is actually a more flexible solution that offers some unique advantages over Intel. Instead of copying a section of HDD data to the SSD cache, StoreMI combines the total available storage space of both the HDD and SSD, and is able to seamlessly shuffle the more active data blocks to the SSD. StoreMI also offers more cache capacity than Intel - up to 512 256GB SSD caches are possible (60GB limit on Intel). Lastly, the user can opt to donate 2GB of RAM as an additional caching layer.
