AMD StoreMI V2, the software now supports 400 series chipsets
StoreMI is a solution. storage tiering that allows you to merge SSDs and HDDs (or slower SSDs with faster SSDs) into one virtual drive. StoreMI takes care of the data transfer between the two storage solutions, then analyzes the data and moves the most frequently used ones to the faster SSD. In fact, this technique combines the capacity and price advantages of HDDs with the speed of SSDs. This results in higher overall system performance, thanks to faster application and game load times.
AMD's original StoreMI software had some issues. Specifically, it was a tiered solution, which meant that it transferred data from slow SSD / HDD to faster SSD drive, but didn't keep a copy of the data on both drives. This had the advantage of making the entire storage capacity of both drives usable, but if the StoreMI virtual partition was damaged for any reason, all data stored on the fastest drive would be lost.
