Intel Optane Memory is a smart memory technology that accelerates a computer’s responsiveness. It is designed to increase computers’ hard drive speed. Intel Optane Memory remembers your frequently used document and apps, enabling you to access these documents with lesser load time.

Sometimes, when running on a computer using an Intel Optane Memory, you may get the error message, Intel Optane™ Memory Pinning Unable to load DLL’ iaStorAfsServiceApi.dll” (Exception from HRESULT: 0x8007007E).
