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.

DOA 6/15/2020 10:45:36 PM

Pros: None

Cons: Wouldn’t even start up but power was going to board. Upgraded motherboard and nothing powered on except for the lights on keyboard and mouse. Hooked up old motherboard and everything started up. Seems to be a hit or miss with this board.
