Legit Reviews published a review on Intel Optane Memory with a secondary harddrive
A quote from the article:
Last month, Intel revealed a number of changes to help promote their Optane Memory line. You know what Intel Optane Memory is right? Intel Optane Memory comes on a M.2 2280 ‘gumstick’ drive and has super fast Intel 3D Xpoint memory chips on it. Once installed into an open M.2 slot, Intel software allows you to cache slower SATA based storage devices like hard drives. By adding a non-volatile (retains data when powered off) cache to a spinning disk you’ll end up with faster response times and have ‘SSD like’ performance in a wide range of applications. Intel offers 16GB, 32GB and 64GB Optane Memory modules and bigger is better as it allows for the storing of more of your most frequently used data. If you have a hard drive and are looking for a way to speed up game load times, content creation applications, improve your web browsing experience and open and close pretty much every app known, an Intel Optane Memory module could be your savior. The best thing is that pricing starts at just $24.99 shipped, so it’s an affordable upgrade and thankfully very simple to install.Intel Optane Memory Tested With Secondary Hard Drive
