This could be incredibly interesting in a lot of ways... I wonder how this will affect the likes of database servers that have been highly optimized to treat disk and ram very differently... What kind of boon to memory mapped databases would this be?<p>I'm guessing that the best initial use cases for this would likely be Amazon, MS, Facebook and Google... I can imagine a server blade that has a low-power CPU, and a TB of XPoint memory with many hundreds to a rack. I would think that on a large scale C* and other bigtable solutions would see incredible gains.<p>Once other RDBMS are better (de)optimized for such a system, they would see huge gains too.<p>I don't know that this will leak into personal computing nearly as soon. Low cost is all relative, and even SSDs are still pretty costly when you need several TB of storage compared to HDDs.
Is this similar to HP's memrister effort reported in Wired recently? Sounds like it. "Memory with the density of Flash and speed of RAM."
