With nearly 60% of organizations using flash storage already, it's clear this trend is here to stay.

To understand the market, we need to understand how we got to where we are today. The last few decades have had near linear growth of CPU performance and almost flat growth of storage performance. The advent of NAND flash helped close the gap, but CPU remains woefully underutilized due to legacy storage protocols and software. Persistent memory hopes to bridge that performance gap in the enterprise data center, but in any immature market, there is a lot of hype and market confusion to be wary of.
