Fail story: I have SSD + HDD caching for Windows ( <a href="https:&#x2F;&#x2F;diskache.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;diskache.io&#x2F;</a> ). But due to lack of marketing skills, and, perhaps, lack of common store for system software for Windows, even free Beta version has been downloaded by like 3.5 people during 3 months of availability.
