Hot Hardware published a review on the Intel And Micron Jointly Drop Disruptive, Game-Changing 3D XPoint (Cross Point) Memory, 1000x Faster Than NAND A quote from the article:

This is something many people thought was impossible," exclaimed Intel Senior Vice President Rob Crooke. During an invite-only press conference, Crooke along with Micron CEO Mark Durcan revealed a radically new class of storage and memory architecture called 3D XPoint (pronounced "Cross Point"). To say this is a game-changer would be the understatement of the year.

Get this: 3D XPoint is 1000 times faster than NAND, boasts 1000x the endurance of NAND, and is 10 times more dense than conventional memory. Consider that existing NAND flash storage is 1000 times faster than traditional mechanical hard drives. We'll give you a minute to process that.
