AMD's Store Machine Intelligence Technology seeks to create a hybrid better than the sum of its parts, combining the low cost of cold spinning rust with the speed of hot flash based drives.  The implementation is not the same as Intel's SRT which treats your SSD as a cache to move frequently used files to the SSD but instead works like a tiered storage system.  That indicates entire files are moving from hot storage to cold storage as their usage patterns change and are not constantly being rebuilt. 

From the testing which [H]ard|OCP did, the machine intelligence part of StorMI lives up to its name, and the installation and configuration are very well done, to the point where they declare Intel's Rapid Storage Technology to be outclassed and should not even be considered as competition to AMD's storage stacking skills.

"AMD’s StoreMI or (Store Machine Intelligence Technology) is storage performance enhancement technology, which can accelerate the responsiveness and the perceived speed of mechanical storage devices to SSD levels. This isn’t exactly a new concept, but AMD’s approach to this implementation is different than what we’ve seen in the past."
