In his Aorus X470 review intro, HEXUS Editor Tarinder mentioned the new AMD StoreMI Technology, a storage-amalgamating technology that is separately marketed as Enmotus FuzeDrive. To recap, AMD StoreMI combines the storage in your PC into one drive and optimises it by moving the most commonly used files to the fastest storage medium. The whole process is invisible to the end user and to install this software you don't even have to re-install your OS, even if you add drives(s) to the system.

AMD now has a dedicated technologies page where it talks about StoreMI Technology. Importantly it says that "AMD StoreMI Technology is included with every Socket AM4 motherboard that features an AMD 400-series chipset," and supplies a free download link and user guide at the foot of this same page. RAM-wealthy users might also be tempted to set an optional DRAM cache of up to 2GB. StoreMI utilizes only about 1-2 per cent of the CPU for 'machine intelligence' and so on.
