Video, Audio Storage Requirements to Boost Hard Drive Density: IHS
Demand for audio and video storage is driving innovation in the hard disk drive space, according to an IHS report.During the five-year period from 2011 to 2016, hard disk drive areal densities are expected to more than double, thanks to growing video and audio storage requirements, a report from IT analytics firm IHS indicates. Areal density is the amount of data that can be physically stored in a given amount of space on a platter inside an HDD. According to the companys Storage Space Market Brief report, continued need for video and audio storage space will drive the five-year compound annual growth rate (CAGR) for HDD areal densities to 19 percent. The report projected data-storage capacities would climb to a maximum 1,800 Gigabits (Gb) per square inch per platter by 2016, up from 744 Gb per square inch in 2011.
The rise in areal density will pave the way for continued growth of the HDD industry, Fang Zhang, analyst for storage systems at HIS, said in a prepared statement. Densities will double during the next five years, despite technical difficulties associated with the perpendicular magnetic recording (PMR) technology now used to create higher-areal-density hard disks. In particular, growth opportunities will lie in applications associated with mass enterprise storage requirements, gaming and in digital video recorders (DVRs) where massive capacity is required to store high-definition video.
