Storage with the speed of memory? XPoint, XPoint, that's our plan

Chris,

Well I guess some of the comments on your last XPoint rant article (... Intel's XPoint emperor has no clothes, only soiled diapers) impacted you enough to write something a bit more objective and useful for you audience. I do high performance programming for a high living and thus XPoint (when it hits the commercial market) will be gladly welcomed even if the initial perf is 10X better than current top of line NVMe PCIe SSDs. When SCM XPoint Dimms arrive, us programmers can then begin to figure out having access to reasonably fast persistent memory changes how systems are designed. Perhaps we can begin to get away from the current trend of complex quorum schemes.

one potential over statement generates complete nonsense

Chris,

Your commentary and analysis are a bit mind boggling. If Intel failed to deliver 1000X but ended up at 10X or greater on latency and IOPS I would argue that I'd take it every day of the week with a big smile on my face.

In modern systems with CPUs galore and 100Gb NICS around the corner, the storage latency and throughput are still huge bottlenecks that cause developers to waste time trying to avoid and/or skip at the expense of fault tolerance. A 10X reduction in latency on storage via NVMe is hugely welcome and will allow great programmers to push the envelope of what systems can accomplish.

I don't think you should be bashing the numbers but instead you should be complaining about delivery dates which seemed to be pushed back and never definitive. I, like many fellow developers, wanted this stuff the day it was announced and waiting over a year to get something is worth complaining about. >= 10X on NVMe is surely not something to complain about regardless if Intel said 1000X. Lastly, I would bet the numbers of XPoint DIMMs will far exceed the NVMe numbers.
