AMD StoreMI Technology A powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single fast easy-to-manage drive. SSDs are fast but expensive and offer minimal capacity. Mechanical hard drives boast large capacity for a low price but are much slower than an SSD. AMD StoreMI technology combines these two types of storage into a single drive and automatically moves the data you access the most to the SSD so you get the best of both worlds SSD responsiveness and mechanical hard disk capacity. You can also use up to 2GB of RAM as a last-level cache for ultra-fast data. Ultra M.2 32 Gb/s (PCIe Gen3 x4 and; SATA3) The PCIe Gen3 x4 Ultra M.2 interface pushes data transfer speeds up to 32Gb/s. In addition it also supports SATA3 6Gb/s M.2 modules and is compatible with ASRocks U.2 Kit for installing some of the worlds fastest U.2 PCIe Gen3 x4 SSDs. Features .
