The introduction of the new Optane family of memory drives comes after years of development and promise to bury the traditional hard drive. In fact, Intel seemed to indicate that its non-volatile XPoint 3D memories might even make it difficult for successful SSDs.
Things are not so clear now that the first units have reached both the business market and the end user market. At least in the second case we find small units and whose advantages, no matter what Intel says, show no revolution in the current market. It seems rather that Intel wants to invent a solution to a problem that (already) does not exist.
