In its most basic form, RAID technology combines disk drives to increase data protection and storage performance. While the basic RAID concept has been around for two decades, the technology has evolved to provide more levels of redundancy in response to growing storage capacity issues. Still, understanding the basics of this technology is just as important as keeping up with new trends.
In the podcast, Arun Taneja, founder and consulting analyst at Hopkinton, Mass.-based Taneja Group, discusses the basic principles of what makes RAID such an effective enterprise data storage technology.
