This week’s episode is the first in a series from Flash Memory Summit 2019. Chris catches up with Erik Kaulberg from INFINIDAT to discuss how the expanding hierarchy of solid-state storage media will drive new products and solutions in the future.

The topics of conversation cover how media has diversified, with new solutions like MRAM and 3D-XPoint. At the same time, we hear that 5-level NAND could be a reality. How are vendors combining these products with traditional storage?

Will the ability to learn from the field with the deployment of traditional storage designs, provide an advantage over SDS? Will vendors selling both hardware and software solutions have an advantage over those only playing in one market? These are just some of this week’s topics of conversation.
