"The quest for low storage latency changes everything" - Rick Coulson of Intel

About the talk:
After decades of relatively static storage latency, high performance devices like SSDs have burst onto the scene. But even with SSDs, storage performance is still a bottleneck in many computer systems. Storage Class Memory promises much faster media, and with 3D Xpoint™ technology, the first storage class memory is entering production. But fast media is not enough. The continuing quest for low storage latency changes nearly everything in computing platforms, from IO bus protocols to new instruction sets. This talk will review the history of storage performance and the compute platform changes driven by SCM (3D Xpoint Technology as an example) and the drive for lower storage latency.
