In today's market, organizations are demanding higher storage performance for their active data sets to accelerate existing applications and provide a foundation for their next-generation 3rd Platform applications (e.g., social, mobile, cloud, and big data). Traditional HDDs have provided performance and enough storage capacity up to this point; however, flash has surpassed HDD in providing an economic solution for high storage performance when $/IOP is considered.
Demands for higher performance and the economics of flash are fueling the growth of flash drives as IDC forecasts the I/O intensive segment (SSD and flash) is growing the fastest by capacity at a 74.3% CAGR through 2017. The market demand for performance with flash, as forecast by IDC in the I/O-intensive segment, will begin to strain storage architectures designed for performance- and capacity-optimized HDDs.
In this white paper, IDC examines the evolution of storage controllers, from traditional HDD controllers to "hybrid array" (i.e., traditional storage arrays that can accommodate flash drives) controllers capable of optimizing flash media and multi core CPUs.
